Question

If two angles of a triangle have equal measures and the third angle measures 90°, what are the angle measures of the triangle?

Answer 1

let the two angles which have same measures be x

Now,

as we know that the sum of all angles of a triangle is 180

then 

180  = x+x+90

180 = 90 +2x

180-90=  2x

90= 2x

90/2 =x


45= x

then the other two angles are 45 and 45

all angles are  90 , 45 and 45



i hope this will help you

Answer 2

Hey friend,Harish here.

Here is your answer :

Let the equal angle be x.

The measure of another angle = 90°

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

So, x + x + 90° = 180°
 
 => 2x  = 180° - 90°

=> 2x = 90°

=>x = 45°

∴ The angles of the triangles are 45°,45°,90°
