Question

One of the angles of a right angled triangle is 40°. Find the other angles of the triangle.​

Answer 1

Step-by-step explanation:

x+x+40=90

2x+40=90

2x=90-40

2x=50

x=50

2

x=25

Answer 2

Here on angle of the right angled triangle is given to be 40°

We have to find the other two angles

Now, as it is a right angled triangle, the other angle will be 90°

Let the third angle be x

We know that sum of all angles in a triangle is 180°

So, x + 90 + 40 = 180

x + 130 = 180

x = 180 - 130

x = 50

Hence, the other two angles will be 90° and 50°
