Answer:
30 ft
Step-by-step explanation:
This is a classic right triangle problem, where the length of the ladder represents the hypotenuse, where the ladder is lengthwise from the building is the base of the triangle, and what we are looking for is the height of the triangle. Pythagorean's Theorem will help us find this length.
so
1024 - 100 = y^2 and
y = 30.4 so 30 feet
It’s going up by 2/9 . if you did it for the first one it’d b 3/9 which is 1/3
Answer:
- ∠B and ∠F
- ∠F and ∠E . . . already listed in the problem statement, so may not be considered an "other pair"
Step-by-step explanation:
∠C and ∠F are vertical angles, so are congruent. Then any angle complementary to one of those will also be complementary to the other.
Likewise, ∠B and ∠E are vertical angles and congruent. Any angle complementary to one of them will also be complementary to the other. Here, ∠E and ∠F are listed as complementary, so we know ∠B and ∠F will be also.

The area of the trapezoid is 43.5 inches²
Step-by-step explanation:
The formula of the area of a trapezoid is
, where:
and
are the two parallel bases- h is its height
∵
=
feet
∵
= 14 inches
∵ h = 3 inches
- Change the length of
from feet to inches
∵ 1 foot = 12 inches
∴
feet =
× 12 = 15 inches
∴
= 15 inches
Substitute the values of
,
and h in the
formula of the area
∴ 
∴ A = 43.5 inches²
The area of the trapezoid is 43.5 inches²
