Problema Solution
the second angle of a triangle is 3 times as large as the first. The third angle is 65 more than the first. Find the measure of the smallest angle.
Answer provided by our tutors
Let the first angle be x.
Then,
x+ 3x+65+x=180
or, 5x+65=180
or, 5x=180-65
or, 5x=115
or, x=115/5=23
Therefore, Answer=23
