what is the angle of measure B in degrees?

∠B is 61°

Step-by-step explanation:

All the angles in a triangle always add up to 180°. We know one of the angles is 51° and another is 180°-112° which is 68°. To find the remaining angle, we need to subtract 51° & 68° from 180°.

180°-68°-51°=61°

The missing angle is 61°

109

Step-by-step explanation:

we know that angle c is 180-112 because it is supplementary to the angle '112'.

So angle c is 68 degrees.

It is given that one of the angles in the triangle is 51 degrees.

By the triangle sum theorem, angle A is 180-51-68. So angle B is 71

Angle A and B are supplementary so angle B is 180 - 71.

Angle B is 109

I hope this helped and I would appreciate the brainliest :)

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25
