Answer:
m∠1 = 71°
Step-by-step explanation:
Angle 1 and 2 are complementary, meaning the measures of the two angles add up to 90°.
Set the measures of the two angles equal to 90°
Combine like terms
Solve for x
Plug the value of 'x' back into the given equation for the measure of angle 1
m∠1 = 71°
Step-by-step explanation:
(x+2y)²=x²+4xy+4y²
...........
You simplify
4i(2-i)(5+31)
And you get
144+288i
2, 222 bc if 200 is in the hundreds then all the digits are the same so therefore it's 2,222
