Answer:
it's architecture.
Step-by-step explanation:
I took the test
X+y=57
x-y=33
make first one in x= form
x=-y+57
x-y=33
-y+57-y=33
-2y+57=33
-2y=-24
y=12
plug in to find x
x-y=33
x-12=33
x=45
Answer:
Step-by-step explanation:
Let x be the unknown angle.
We know that x+50=120 because the value of an exterior angle of a triangle is equal to the sum of the other 2 interior angles.
x+50 = 120
Subtract both sides by 50
x = 70
The value of the unknown angle is 70 degrees.
Have an awesome day! :)
