Triangle ABC is a right triangle, and angles A and C are equal but not right angles. What is the measure of angle B ?
A) 30 degrees
B) 45 degrees
C) 60 degrees
D) 90 degrees

D)

Step-by-step explanation:

Angle A and C are equal i.e. 45°

So angle B will definitely be 90°

Good evening

Step-by-step explanation:

we have two statements here:

statement 1: A and C are not right angles

statement 2: ABC is a right triangle

according to the statements above :

the triangle ABC is right at point B.

check the attached picrude.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
