Question

two angles of a right traingle are equal.what is the measure of this angle?(a)70° (b) 40°(c)45°(d)100°​

Answer 1

Answer:

(c)45°

Step-by-step explanation:

Let the equal angles of right triangle be x° and x°.

= x°+x°+90°= 180°

= 2x°+90°= 180°

= 2x°= 180°-90°

= 2x°= 90°

= x= 90°/2

= x= 45°

Answer 2

Answer:

c) 45°

Step-by-step explanation:

Let the two equal sides of a right triangle be = a°

☆ The sum of all the angles of a triangle is 180°

a° + a° + 90° = 180°

2a° + 90° = 180°

2a° = 180°- 90°

2a° = 90°

a = 90°/2

a = 45°

Hence,the measure of each remaining angles of the right triangle is 45°.
