Question

find the size of unknown angle

Answer 1

Answer:

Step 1: Determine the measure of the angle adjacent to 148°.

The two angles make a straight line and therefore have a sum of 180°.

180° - 148° = 32°

Step 2: Add together the two known angles inside the triangle.

56° + 32° = 88°

Step 3: Subtract the sum from 180°.

180° - 88° = 92°

The measure of angle h is 92°.

Answer 2

D) As the given angle is 40 degrees, then, Complement is 50 degrees.

E)The complement is the angle that has to be added to make 90°. So the supplement of 110° is 70° because 110 + 70 = 180.
