Question

Find the measure of the third angle if two of the acute angles measure 40° each​

Answer 1

In an right angled triangle,

θ

1

+θ

2

=90°

40°+θ

2

=90°

θ

2

=50°

Thus, the other acute angle is 50°

Answer 2

Answer:

100°

Step-by-step explanation:

= Angle₁ + Angle₂ + Angle₃ = 180    [Angle Sum Property Of Triangle]

Let the Angle₃ be h

= 40° + 40° + h = 180°

= 80° + h = 180°

= h = 180° - 80°

= h = 100°

∴Angle₃ or Third angle is 100°
