Answer:
A.
Just plug in each point for the x and y and find which point is valid
Step-by-step explanation:
5(15)+(15)(15)=75+225
=300
The 2 angles add up to 90 degrees so
x + y = 90, also:-
x - y = 72 (given)
adding the 2 equations:-
2x = 162
x = 81
and therefore
y + 81 = 90
y = 9
Answer the 2 angles are 81 and 9 degrees
Answer:
a. infinite solutions, answer is x = 30, identity equation
b. no solution, a contradiction equation
