Question

11. In a right-angled triangle if one of the acute angles measures 40°, find the measure of the
acute angles
​

Answer 1

Step-by-step explanation:

In right angle triangle

Let angle B be 90°

and A be 40°

sum of all angles of triangle is 180°

130° +x = 180°

x= 50°

Answer 2

Answer:

The other acute angle is 50°

Step-by-step explanation:

Sum of all angles of a triangle is 180°.

One is 90° [ °•° A right angled ]

One acute angle is 40°

Then the other is = 180° - ( 90° + 40° )

= 180° - 130°

= 50°
