The proper angle for a ladder is about 75' from the ground. Suppose you have a 21 foot ladder. How high
can it reach?
The ladder gets propped against the house, making a 75 degree angle with the ground. We can use the fact that cos(75°)=base distance/length of ladder to figure out the length of the base. Multiplying both sides by length of ladder we get, length of ladder×cos(75°)=base distance.Nov 6, 2019

Answer:
The angle x, has the measurement of 40°
Step-by-step explanation:
Step 1: Define complementary angles
Complementary Angles: Two angles are complementary when the sum of them is equal to 90°. For example, 30° and 60° are complementary because they add up to 90°.
Step 2: Figure out the complementary angle
Since ∠ABD and ∠DBC are complementary, that means that they should add up to 90°. Since the angle value of ∠ABD is 50°, that means that the angle value of ∠DBC should be 90° - 50° = x.
90° - 50° = x
40° = x
Answer: The angle x, has the measurement of 40°
Draw a square ABCD with A(0,6), B(4,6), C(0,10), and D(4,10)
Reflect it on the vertical line through 6 on the horizontal axis to get

Determine whether the equation has one solution, no solution, or infinite solutions.
Explain your reasoning.
9x + 2 = -4(x + 6)
Answer:
The equation has 1 solution.
Step-by-step explanation:
Because you don't get the same answer on both sides, this equation does not have infinately many solutions. Because you don't get an invalid answer, such as 1 = 0, this equation doesn't have one solution. When you solve this equation, you'd get something similar to this
9x-2 = -4x-24 (distributive property)
13x-2=-24 (combine like terms)
13x=-22 (additive property of inversion)
x = -22/13
which is a valid, real-world solution.

Step-by-step explanation:
2.5x2.5=6.25 then you would do 64 divided 6.25 to get 10.24 which would give you 10 whole windows.
A map has a scale 1/2 in.= 60 mi. If two cities are 2 inches apart on the map, hoy many miles separate de cities?
Answer:
240 miles
Step-by-step explanation:
1/2 + 1/2 + 1/2 + 1/2 = 2
60 + 60 + 60 + 60 or 60 * 4 = 240
NEED HELP ASAP 2 questions WORTH 50
Answer:
The first question tan(24) = x/12 because tan(x) = opposite/adjacent
so x in radians ≈ -25.618....
x in degrees ≈ 5.342....
For the second question tan(72) = x/20
x in radians ≈ -5.248....
x in degrees ≈ 61.553....
Answer:
for first one
relationship between base and perpendicular is given by tan angle
tan24=p/b
tan24=x/12
x=tan24×12=5.34
Step-by-step explanation:
for second one
relationship between base and perpendicular is given by tan angle
tan72=x/20
x=tan72×20=61.55

What is the measure of < c in quadrilateral ABCD?
Answer:
the sum of interior angles of a quadrilateral = 360 degree
Step-by-step explanation:
therefore,
let the angle C be X
124 + 96 + 94 + X = 360
314 + X = 360°
X = 360 - 314 = 46°
angle C = 46°
Answer:
46 degrees

Answer:
f(x) = 3x + 1
Step-by-step explanation:
f(x) = 3x + 1
f(1) = 3+1 = 4
f(2) = 3*2 + 1 = 7
f(3) = 3*3 + 1 = 10
f(4) = 3*4 + 1 = 13
