Answer:
The measure of the angles are 55° and 35°
Step-by-step explanation:
Sum of two angles that are complement of each other are 90.
The angles are A and B, so we can write:
A + B = 90
Also,
The difference is 20. Let A be the greater of them, so we can write equation 2 as:
A - B = 20
Now, we add up both equations, eliminate B and solve for A first:
A + B = 90
A - B = 20
---------------
2A = 90 + 20
2A = 110
A = 110/2
A = 55
And now the measure of B:
A + B = 90
55 + B = 90
B = 90 - 55
B = 35

Answer:
She made 2 pans that were divided into 12 pieces. If they ate 1 1/12, they ate 1 full pan, and 1 slice of the 12 of the other pan. Leaving 11 pieces left.
Step-by-step explanation:
Use law of cosine: 16²=17²+12²-2*17*12cosY
408cosY=17²+12²-16²=177
cosY=177/408
use your calculator to find Y: Y≈64
