Answer:
MON = 130°
Step-by-step explanation:
LOM + MON = 180°
In other words
4z + 30° + 8z + 90 = 180°
12z + 120 = 180
60 = 12z
z = 5
5 x 8 = 40 + 90 = 130°
Answer:
A = 48 ft²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A =
bh ( b is the base and h the perpendicular height )
here b = 16 and h = 6 , then
A =
× 16 × 6 = 8 × 6 = 48 ft²
Perimeter = 2 width + 2 height
P = 2w + 2(20)
P = 2w + 40
then the answer is B
