Question

4.The angles of a triangle are in the ratio 3: 2: 7. Find largest angle.​

Answer 1

Answer: 105

Step-by-step explanation:

3:2:7=180

180/sum of the parts(ratio)

180/12=15

One part is 15, so

3:2:7=45:30:105

45+30+105=180

Answer 2

Sum of the three angles in a triangle is 180°.

3x+2x+7x=180°

12x=180°

X=15°

3x=45°,2x=30°,7x=105°

Therefore,7x is the largest angle.
