An architect designs a modern building facade using triangular glass panels. Each triangle has angles in the ratio 2:3:7. What is the measure of the largest angle in the panel?
Show answer & explanation
Correct answer: B
Explanation
Given:
The ratio of the angles of a triangle = 2 : 3 : 7
By the formula:
The sum of the angles of a triangle = 180°
Total ratio = 2 + 3 + 7 = 12
1st part = 180 / 12 = 15°
Largest angle = 7 × 15 = 105°
