Composite figure is made up of 4 triangles and a square.
Area of Square = Length x Length
Area of Square = 12 x 12
Area of Square= 144 cm²
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 12 x 8
Area of triangle = 48 cm²
Area of 4 Triangles = 48 x 4
Area of 4 Triangles = 192 cm²
Total Area = 144 + 192 = 336 cm²
Answer:
D:21
Step-by-step explanation:
Use the vertical angles equation.
4x + 13 = 5x - 8
Subtract 4x from 5x.
5x - 4x = x
13 = x - 8
Add 8 on both dies.
13 + 8 = 21
x = 21
JKLM has x that equals 21.
<JKLM and <LMJK equal 97 degrees.
