Hello, I need help on this :)

Enter a number/answer

What is the measurement of b?

21

Step-by-step explanation:

The rule for a right triangle is (x^2)x(y^2)=(z^2)

so 20 squared is 400 and 29 squared is 841.

And since the side with the length 29 is the hypotenuse.

It is 400 + = 841

841-400=441

the square root of 441 is 21

see explanation

Step-by-step explanation:

3x and 144 are adjacent angles on a straight line and sum to 180°

3x + 144 = 180 ( subtract 144 from both sides )

3x = 36 ← value of 3x

divide both sides by 3

x = 12

and

2y - 5 and 95 are vertically opposite angles and are congruent, so

2y - 5 = 95 ← value of 2y - 5

add 5 to both sides

2y = 100 ( divide both sides by 2 )

y = 50

Then

x + y = 12 + 50 = 62
