Question

the three angle of a triangle are x-35°,x-20°,x+40°. And please it urgent.

Answer 1

Given the angle of triangles:-
x-35°,x-20°,x+40°

As we know that sum of triangles is 180°

Then,
x-35 +x-20 +x+40=180
=>3x-15=180
=>3x=180+15
=>3x=195
=>x=195/3
=>x=65°


Angles are

x-30°=65°-30°=35°
x-20°=65°-20°=45°
x+40°=65°+40°=105°
