Question

Of the three angles of a triangle, the second is one-third of the first and the third is 26° mone
than the first. What are the measures of these angles?​

Answer 1

Answer:

Step-by-step explanation:

Sum of angles of  triangle = 180.

Let angles be a,b,c .

a + b + c = 180 --- (1)

b = 1/3 a => 3b = a;

c = a + 26 => c = 3b + 26;

Substituting values of a,b,c in eqn 1.

3b + b + 3b + 26 = 180

b = 22.

a = 66

c = 92
