Answer:
Step-by-step explanation: For any triangle, the angles add to 180 degrees
A+B+C = 180
68+46+C = 180
114+C = 180
C+114 = 180
C+114-114 = 180-114
C = 66
Angle C is 66 degrees
Angle C' is 66 degrees
The triangles ABC and A'B'C' are similar, so angle C = angle C'

What is the slope of a line that is parallel to the line joining (7,-5) and (-5,7)
Answer:
Step-by-step explanation:
If two lines are parallel then they will have the same slope. So all you need to do is find the slope of the line that joins the two given points. You can use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. You can also graph the two points and use rise over run. [tex]\frac{7-(-5)}{-5-7} =\frac{12}{-12}=-1[/tex]
-1 is the slope of a line that is parallel to the line joining (7,-5) and (-5,7)
What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given, a line that is parallel to the line joining (7,-5) and (-5,7)
Since lines are parallel to each other thus their slope will be the same.
From the general formula of slope:
Slope = (y₂ - y₁)/(x₂ - x₁)
Slope = (7 + 5)/ -5 - 7)
Slope = -1
Therefore, the slope of a line that is parallel to the line joining (7,-5) and (-5,7) is -1.

Determine the missing y value if the slope of a line is 4/3 and the line passes through the points (5,x) and (2,-3)
Answer:
x = -7
Step-by-step explanation:
Given parameters:
Slope of the line = [tex]\frac{4}{3}[/tex]
Coordinates = (5,x) and (2,-3)
Unknown:
X= ?
Solution:
To find slope, use the expression below;
Slope = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
y₂ = -3 y₁ = x
x₂ = 2 x₁ = 5
[tex]\frac{4}{3}[/tex] = [tex]\frac{-3 - x}{2 - 5}[/tex]
3(-3-x) = 4(-3)
-9 -3x = 12
-3x = 21

for the graph of g(x) pictured below, over which of the following intervals is g(x) only decreasing?
Answer:
2. -8 < x < -2
Step-by-step explanation:
The x-values of the line where the line slants downwards before it begins to slant upwards to the right, is the interval at which g(x) is decreasing only.
From the graph, at x = -8, y = -2. When x = -2, y = -5.
Between the intervals of x = -8 and x = -2, g(x) decreased from -2 to -5.
Therefore, the answer is: 2. -8 < x < -2

The measures of the angles of a triangle are shown in the figure below. Solve for x.
51
Answer: x=
Submit Answer
attempt 1 out of 2
Answer:
x = 39°
Step-by-step explanation:
The triangle shown is a right angle triangle having angles 90°, 51° and x°.
Sum of interior angles of a triangle = 180°, therefore:
[tex] 90 + 51 + x = 180 [/tex]
Add like terms
[tex] 141 + x = 180 [/tex]
Subtract 141 from each side
[tex] 141 + x - 141 = 180 - 141 [/tex]
[tex] x = 39 [/tex]
x = 39°
Benjamin is planning to make scale drawings of bat wings. He wants all of his drawings to use the same scale. He says he can use the equation d=1.5w to find the length of a scale drawing, d, based on the length of the bat wing, w. What is fhe scale factor of a bat wing length to scale drawing length? Explain.
Answer:
[tex]1.5[/tex] is the scale factor of a bat wing length to scale drawing length.
Step-by-step explanation:
A scale factor is a number which multiplies (scales) , some quantity. In the equation [tex]y=kx[/tex], [tex]k[/tex] is the scale factor for [tex]x[/tex]. Here, [tex]k[/tex] is called as the constant of proportionality of [tex]y[/tex] to [tex]x[/tex].
Consider the equation [tex]d=1.5w[/tex]
Here, d denotes the length of a scale drawing and w denotes the length of the bat wing.
So,
[tex]1.5[/tex] is the scale factor of a bat wing length to scale drawing length.

Burj Khalifa is about feet tall. Q1 Tower is about feet tall. The Shard is about feet tall. Willis Tower is about feet tall. Gran Torre is about feet tall.
Complete question :
Continent _________building _height(m)
________Carlton center office tower _ 223m
_________ burj Khalifa ____________828m
_________ QI ________________323
_________ the shard _________310
_________ Willis tower _______442
_________ grand torre ______300
Answer:
Kindly check explanation
Step-by-step explanation:
1 meter is approximately 3.28 feets
Height of the buildings in feets is obtained by multiplying the height in meters by 3.28
Carlton center office tower = (223 * 3.28) = 731.44 feets
Burj Khalifa = (828 * 3.28) = 2715.84 feets
QI = (323 * 3.28) = 1059.44 feets
The Shard = (310 * 3.28) = 1016.8 feets
Willis tower = (442 * 3.28) = 1449.76 feets
Grand Torre = (300 * 3.28) = 984 feets

15= 3x−15 what is x?
Answer:
x = 10
Step-by-step explanation:
Original Equation:
15 = 3x - 15
Add 15 to both sides
30 = 3x
Divide both sides by 3
10 = x

Please consider Brainliest :)
x = 10
All you have to do is add 15 to both sides, and you have
30 =3x
and divide by 3
you get
10 = x
The sum of two complementary angles is 90° Angle A is represented by 3x - 10, and Angle B is represented by x. Solve for x Hint: combine the 2 angles and set equal to 90
Angle A = 3x - 10
Angle B = x
Their angle sum = 90° ( complementary angles form 90° )
This can be written in an equation as =
= 3x - 10 + x = 90
= 3x + × + ( -10 ) = 90
= 4x + (-10) = 90
= 4x = 90 + 10 ( transposing-10 from LHS to RHS changes-10 to +10 )
= 4x = 100
= x = 100 ÷ 4 ( transposing ×4 from LHS to RHS changes ×4 to ÷4 )
= x = 25
Angle A = 3x - 10
= 3 × 25 - 10
= 75 - 10
= Angle A = 65°
Angle B = x = 25°
Their sum = 65 + 25 = 90°
Therefore , the complementary angles , Angle A = 65° and Angle B = 25° .
