Answer:
Step-by-step explanation:
Base = 25 ft
height = 8 ft
Area of triangle =
100 ft²
The area (A) of the triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
Here b = 25 ( parallel to the base of the rectangle ) and h = 8, then
A = × 25 × 8 = 12.5 × 8 = 100 ft²
BCD= 15
3x-15+?=180
3x=180
x=60
3(60)-15=180
180-15=165
yes
