In a triangle, 1 angle is 40 degrees and the other is 3/8 times larger, calculated the value of 3 angles

Let’s find the measure of the second angle in this triangle, for this we need to increase the measure of the first angle in this triangle by 3 1/8 times:

40 ° * 3 1/8 = 125 ° is such a measure of the second angle in this triangle;

Let’s find the measure of the third angle in this triangle, for this we need to subtract the measure of the first angle from 180 ° and subtract the measure of the second angle in this triangle:

180 ° – 40 ° – 125 ° = 15 ° is such a measure of the third angle in this triangle.

Answer: 15 ° is such a measure of the third angle in this triangle.
