1) 22.5
2) 16
Hope it helps sorry I cant do all of them
Answer:
x = -7, y = -9
Step-by-step explanation:
The coefficient (the number before) the y is the same but the signs are opposite so add the equations together:
x-3x+y-y=-16+30
-2x=14
x=-7
y=-16-x=-16--7=-9
I would say 16 that’s what it is most likely
The interior angles of any triangle add up to 180º in measure. So we have
4x + (2x + 10º) + (x - 5º) = 180º
Solve for x:
7x + 5º = 180º
7x = 175º
x = 25º
