Angle a and b are supplementary. angle a has a measure 80 what measure of angle b the measure of angle b is

∠B = 100°

Step-by-step explanation:

Supplementary angles have a sum of 180°, thus

A + B = 180, that is

80 + B = 180 ( subtract 80 from both sides )

B = 100°

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
