1. Which angle is complementary to angle BAC?

A. ACB

Step-by-step explanation:

Complementary angles are two angles whose measures add up to 90°

So BAC + ACB is 90° because ABC is 90° (the total angles of triangle is 180°)

angle ACB

Basic facts:

complementary angles add up to 90 degrees

angles in a triangle add up to 180

Step-by-step explanation:

it is angle ACB because as we can see the triangle is a right-angle triangle

180-90=90

so we can take out angle ABC

therefore angle BAC and ACB add up to 90

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
