Answer:
x = 20
Step-by-step explanation:
The sum of the given angle expressions is 90°, the measure of the right angle:
x + (3x +10) = 90
4x = 80 . . . . . . . . . subtract 10
x = 20 . . . . . . . . . . divide by 4
Answer:
x = 20
Step-by-step explanation:
Key skills needed: Complementary Angles, Equations
1) We are given this diagram and we want to find out x.
The 2 angles (One with the measure "x degrees" and the other with the measure of "3x+10") are complementary. This means that both their measures add up to equal the measure of a right, or 90 degrees.
2) This means we can make the equation --> [tex]x + 3x + 10 = 90[/tex]
To solve:
Combine like terms (3x + x = 4x) --> [tex]4x + 10 = 90[/tex]
To get "x" by itself, subtract 10 from both sides (90 - 10 = 80)
This means it would be --> [tex]4x = 80[/tex]
Divide by 4 from both sides (80 divided by 4 is 20) and get x = 20
Therefore 20 is your answer.
Hope you understood and have a nice day!! :D

In △ABC, m∠C=95°, a=26, and b=17. Identify c rounded to the nearest tenth.
Answers
Answer:
32.3
Step-by-step explanation:
According to the Law of Cosines, for any △ABC with sides lengths a, b, and c, a2=b2+c2−2bccosA; b2=a2+c2−2ac cosB; and c2=a2+b2−2abcosC.
Set up the equation for the Law of Cosines:
c2=a2+b2−2abcosC
Substitute the known values into the Law of Cosines:
c2=262+172−2(26)(17)cos 95°
Square the values and multiply:
с2=676+289−884cos95°
Add:
c2=965−884cos95°
Take the square root of both sides:
c=965−884cos95°
Calculate the value of cosine 95° on a calculator and solve for the positive value of square root to find c:
c≈32.3
Therefore, c≈32.3.
So, the length of side c is approximately 32.3 units.

On a test, Sarah got 48 questions correct out of 50. What percent did she get on her test?
Answers
Answer:
96%
Step-by-step explanation:
48 / 50 = 0.96
0.96 x 100% = 96%
Sara got a 96% on her test
she got a 48/50. Percentage is 'something'/100. So you * both sides by 2 so 50 is 100 and 48 is 96

For a moving object, the force acting on the object varies directly with the object's acceleration. When a force of 40 N acts on a certain object, the acceleration
of the object is 10 m/s. If the acceleration of the object becomes 6 m/s?, what is the force?
Answers
Answer:
New force = 24 N
Step-by-step explanation:
The force acting on the object varies directly with the object's acceleration
i.e.
[tex]\dfrac{F_1}{F_2}=\dfrac{a_1}{a_2}[/tex] ...(1)
We have,
F₁ = 40 N, a₁ = 10 m/s², a₂ = 6 m/s₂, F₂ =?
Put all the values in equation (1).
[tex]F_2=\dfrac{F_1a_2}{a_1}\\\\F_2=\dfrac{40\times 6}{10}\\\\F_2=24\ N[/tex]
So, the new force becomes 24 N.
