Question

the angles of triangle are ( x+21)°, x and (2x-45) find the value of x and the angles​

Answer 1

answer is 66 degree

Answer 2

Answer:

x=51 and required angles=72°,51° and 57°

Step-by-step explanation:

Angles of the triangle=(x+21)°, x° and (2x-45)°

According to angle sum property:

(x+21)°+x°+(2x-45)°=180°

4x°-24°=180°

x=204/4

x=51

Angles of the triangle:

(x+21)°=(51+21)°=72°

x°=51°

(2x-45)°=(102-45)°=57°
