Question

If one angle of a right angled triangle is 49° , write the

measure of all three angles of this triangle.​

Answer 1

Answer:

Given

1st Angle = 49°

2nd Angle= 90°

As it is right angle triangle so, one of its Angle is 90°.

to find the other angle :-

(By using angle sum property )

49+90+x=180

139+x= 180

x=180-139 = 41

3rd angle is = 41

Answer 2

Question :-

• If one angle of a right angled triangle is 49° , write the measure of all 3 angles of this triangle?

Given :-

• a right angle triangle with one of the angle 49°.

To find :-

• the measure of all 3 angles.

Solution :-

since the triangle is a right angle triangle then the second angle will be 90°.

1st angle = 49°

2nd angle = 90°

let the 3rd angle be x

sum of 3 angles in a triangle is 180°.

==> 49° + 90° + x° = 180°

==> 139° + x° = 180°

==> x° = 180° - 139°

==> x° = 41°

• therefore the measure of three angles are 49° , 90° and 41°.
