Answer:
60
Step-by-step explanation:
find the missing angle in triangle HAI =60.
VERTICALLY OPPOSITE ANGLES ARE EQUAL.=60
Angle x is alternating with the angle.
Answer:
4=4, in infinitely many solutions
Step-by-step explanation:
hope this helps
The answer is (x+1)²= x²+2x+1
so x^2 + 2x must be added 1 to become x²+2x+1=<span>(x+1)²</span>
if ∡3 is a supplementary angle with ∡5, namely they both add up to 180°, then that means that the corresponding angles of ∡1 = ∡5, and ∡3 = ∡7, which means the lines crossing those angles are parallel.
