Question

if ∆PQR angle P + angle Q =135° and angle Q - angle R =20°. then angle P=?
​

Answer 1

Answer:

angle P = 70 degree

Step-by-step explanation:

angle P + angle R + angle Q = 180 degree

135 degree + angle R = 180 degree

angle R = 45 degree

angle Q - angle R = 20 degree

angle Q = 20 + 45 = 65 degree

so angle P = 135 degree- angle Q

= 135 - 65 = 70 degree
