As stated by the triangle angle sum postulate, the measure of angle A+ the measure of angle B+ the measure of angle C= 180, the sum of all triangles no matter what, and if a=59 and b=76, then 59+76+ the measure of angle C=180, then you simplify the left side by adding 59 and 76 to get 135. Then, you subtract 135 from both sides and you will come up with the measure of angle C=45 degrees.

The sum of the angles of ANY triangle on a flat surface is 180 degrees.
So if angle A is 59 degrees and angle C is 76 degrees, angle B has to be 45 degrees.
180-59-76=45

B+59+76=180
B+135=180
B=45 degrees
Check:
45+59+76=180
180=180

B=180-A-C=180-59-76=45 degrees.

For a triangle,the interior angles sum up to 180 degrees.
therefore,
135+B=180
B=180-135
B=45
angle B is 45 degrees.

there are 180 degrees in a triangle
add angle A and C together, then subtract that answer from 180
that's your answer for angle B
59 + 76 = 135
180 - 135 = 45
ANSWER
angle B = 45 degrees
