30/2 = 15
15 x 5 = 75
The number is 75.
The two angles are alternate exterior angles, so they have the same measure.
5x+42=8x-15
5x+57=8x
57=3x
x=19
Answer:
150 ft²
Step-by-step explanation:
Area of trapezoid = ½(a + b)h
Where,
a = 24 ft
b = 24 + 12 = 36 ft
h = √(13² - 12²) = √25 = 5 ft (pythagorean theorem was applied here)
Plug in the values
Area of trapezoid = ½(24 + 36)*5
= ½(60)*5
Area of trapezoid = 150 ft²
B because 67 is not equal to 96
E because 67 is less than 96
