Question

In triangle pqr, p=x, q = x-40 , r= x+10.Calculate angle Q​

Answer 1

hyy there

Step-by-step explanation:

• angles opposite to equal sides are equal so angle P= angle R = x(say)

• 40+x+x=180°(angle sum prop)

• 2x= 140

• x=70°

• so angle P = 70°

Answer 2

Answer:

sum of angles of triangle = 180°

p=x,

q = x-40 ,

r= x+10 ( given)

P + Q + R = 180°

x + x- 40 + x + 10 = 180°

3x -30 = 180°

3x = 180° + 30

3x = 210°

x = 210

3

x = 70°

Therefore Angle Q = 70°
