Question

In the given figure y = ____________________​

Answer 1

Answer:

sum of interior angles of a triangle is 180°

angle R + angle P + angle Q = 180°

angle R + 35° + 45° = 180°

angle R + 80° = 180°

angle R = 180° - 80°

angle R = 100°

angle QRS is a straight angle, which is 180°

angle PRQ + angle PRS = 180°

100° + y = 180°

y = 180° - 100°

y = 80°

Step-by-step explanation:

Answer 2

Answer:

y = 80°

Step-by-step explanation:

Given,

• $\angle{P}$ = 35°
• $\angle{Q}$ = 45°

To find,

• Measure of y°.

Knowledge Required,

• The sum the opposite interior angles of a triangle is equal to the measure of the exterior angle.

Finding y :

35° + 45° = y

→ 80° = y

Hence, the measure of y is 80°.
