Answer:
109 took physics and 392 took Trigonometry
Step-by-step explanation:
(8,6)
Solve by elimination!
-2x-y=-22
2x-6y=-20
cross out, and merge!
-7y=-42
y = 6
Plugin y in one equation (I choose the easy one XD)
-2x-6=-22
-2x=-16
x = 8
please mark me brainliesf if it is right
sin(A)/a = sin(B)/b
x= 1± over 2
90
you put 90
