Question

7. In a right-angled triangle, one angle measures 40°. Find the remaining angles,​

Answer 1

Answer:

50

is the correct ansqer

Answer 2

Given:

• Triangle is right angled triangle
• One angle is 40°

To finD:

• Other two angles

Solution:

We are given one angle is 40° and other is 90° because traingle is right angled.

Now,

• One angle of traingle = 40°
• Second angle of triangle = 90°

We know that according to the angle sum property of triangle sum of all interior angles of triangle is always equal to 180°.

______________

Let suppose that third angle is x.

So,

40°+90°+x = 180° --(angle sum property of triangle)

→ 130° +x = 180°

→ x = 180°-130°

→ x = 50°

Therefore,

• First angle of triangle = 40°
• Second angle of triangle = 90°
• Third angle of triangle = 50°
