Question

anyone please tell me this question​

Answer 1

Answer:

SQR =75 degrees

let PQS be a and SQR be b

now a/b=7/5

5a=7b

a=(7b)/5

a+b=180

7b/5 + b=180

(7b+5b)/5 =180

12b=900

b=900/12

b=75degree

hope it would help dear:))

Answer 2

Answer:

<SQR =75°

Step-by-step explanation:

Let the given ratio be in the x.

so, <PQS =7x and <SQR =5x

According to question, <PQS + <SQR = 180°

= 7x + 5x = 180°

= 12x = 180°

= X = 180° ÷ 12

= X = 15°

Therefore, <SQR = 5X = 5 × 15° = 75°.
