Answer:
105 cm²
Step-by-step explanation:
The figure is composed of a rectangle and a triangle
area of rectangle = 15 × 6 = 90 cm²
area of triangle = bh ( b is the base and h the height )
Here b = 15 - 9 = 6 and h = 11 - 6 = 5 , thus
area of triangle = × 6 × 5 = 3 × 5 = 15 cm²
Total area = 90 + 15 = 105 cm²
Complementary angles add up to 90 degrees.
So we can write:
42 + x = 90
To solve, subtract 42 to both sides:
x = 48
So the complement of a 42 degree angle is a 48 degree angle.
