Question

In ∆ PQR , m L P = 35° , mL R = 60° then mL Q = ________.


a) 55°
b)65°
c)75°
d)85°​

Answer 1

Question:

In ∆ PQR , < P = 35° , < R = 60° then < Q = ________.

a) 55°

b)65°

c)75°

d)85°

Answer:

< P + < R + < Q = 180° (Angle sum property)

When we put in values it becomes:

35° + 60° + < Q = 180°

95° + < Q = 180°

< Q = 180° - 95°

= 85°

Hence, the answer would be:

d) 85°
