Question

Two angles of a triangle are 53 and 67 ,the third angle is

a) 40 b) 50 c) 60 d) 70​

Answer 1

Answer:

Two angles of a triangle are 53 and 67 ,the third angle is

a) 40

b) 50

c) 60 (✓)

d) 70

Explanation:

If you add all three interior angle measures together in a triangle it will always equal 180°.. To find a third angle you will subtract the sum of the two given angles from 180°.

.

Answer 2

Answer:

The third angle is 60

Step-by-step explanation:

Angle A.First angle = 53

Angle B.Second angle = 67

∆A + ∆B - 180°

∆53 + ∆67 - 180°

180° - 120

= 60
