Use Figure 2.1. Harriet Cutter’s gross pay for this week is $555. She is single and claims two allowances. What amount will be withheld from Harriet’s pay for federal income tax?

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

the answer is d

hope this

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
