What is the value of x? a. 19 degrees b. 26 degrees c. 29 degrees d. 109 degrees

a. 19 degrees

Step-by-step explanation:

The angles of a triangle add up to 180 degrees.

This triangle is a right triangle, so it has a 90 degree angle.

The three angles are 90, 71, and x

90+71+x = 180

Combine like terms.

161+x=180

Subtract 161 from each side

161-161 +x =180-161

x =19
