Answer:
m<D = 26
Step-by-step explanation:
Exterior angles thm:
83 + 6x - 4 = 21x + 4
6x + 79 = 21x + 4
6x - 21x = 4 - 79
-15x = -75
x = 5
m<D:
6x - 4
6(5) - 4
30 - 4
26

Answer:
Area of shape = 187 cm²
Step-by-step explanation:
Given:
Length of rectangle = 15 cm
Width of rectangle = 9 cm
Height of triangle = (22-9) cm = 13 cm
Base of triangle = (15-7) cm = 8 cm
Find:
Area of shape
Computation:
Area of shape = Area of rectangle + Area of triangle
Area of shape = (l)(b) + (1/2)(b)(h)
Area of shape = (15)(9) + (1/2)(8)(13)
Area of shape = 135 + 52
Area of shape = 187 cm²
Answer:
What is the area?
Step-by-step explanation:
35.6 minutes
S = v*t = 8 * 40/60 = 16/3 m
=> t = s/v = 16/(3*9) = 35.555555 minutes
