Find the measures of the three angles.

Question

One angle of a triangle is 45° greater than the smallest? angle, and the third angle is 5° less than twice the smallest angle. Find the measures of the three angles.

Answer 1

Let x = measure of smallest angle in the triangle.

Another angle measures x+45.

Third angle measures 2x-5.

 

Add these all up & set = to 180^o

Then solve for x & you'll know, soon, all 3 angles.
