Question

Find B if A = 70 degrees and a + B = 80 degrees

B =

Answer 1

To find the value of B when A = 70 degrees and a + B = 80 degrees, you can use the equation:

B = 80 degrees - A

Substitute the value of A, which is 70 degrees:

B = 80 degrees - 70 degrees

Now, subtract 70 degrees from 80 degrees:

B = 10 degrees

So, B is 10 degrees.
