90°
∠AEF is a right angle
∠CEF is a straight angle
m∠CEF = m∠CEA + m∠BEF
Answer:
=x^4−2x^3−20x^2+46x−21
if you can give me brainliest that would be great :)
M = -9 ; solve for m by simplifying both sides of the equation, then isolating the varible
Answer:
a = (x - b)/2
Step-by-step explanation:
2a + b = x
-b -b
2a = x - b
/2 /2
a = (x - b)/2
for ex:
x = 3
b = 2
a = ((3) - (2))/2 = 0.5
a = 0.5
2a + b = x
2(0.5) + 2 = 3
