Question

2. The angles of a quadrilateral
are in the ratio 2:5:6:7. The
measure of the largest angle is.
O a) 63
O b) 172
O c) 126
O d) None of these​

Answer 1

Answer:

a) 63°

Step-by-step explanation:

Let the angles be x.

According to the question,

2x+5x+6x+7x=180°

20x=180°

x=180°/20

x=9°

2x=2(9)=18°

5x=5(9)=45°

6x=6(9)=54°

7x=7(9)=63°

Therefore, the measure of the largest angle is 63°.
