Answer: 68 degrees
Step-by-step explanation:
The sum of the angles in a triangle is 180 degrees.
Since we are given 2 of the angles, we can set up an equation.
Let the measure of angle G = g.
Then, g + 97 + 15 = 180
g + 112 = 180
g = 68

A contractor purchased 7 dozen pairs of work gloves for 103.32 dollars.
He incorrectly calculated the unit price at 14.76 per pair for his expense report.
Let’s correct his work.
Solutions.
=> 7 pairs for gloves for 103.32 dollars.
Let’s find the cost of each pair of gloves.
=> 103.32 / 7 = 14.76 dollars.
according to our solution, he has a correct answer. The only problem in his work is the Unit rate representation.
=> 14.76 dollars/pair
