Answer:
83 degrees
Step-by-step explanation:
The angles 56 and 41 plus the one in between should add up to 180 degrees. So you do 180 - 56 - 41 = 83.
83 and x are vertical angles so they are the same measure.
<x = 83 degrees

Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x = 7,3
Answer:
1) f(x) = x/8 - 7
2) f(x) = 1 - x/3
3) f(x) = 20 - 0.25x
4) f(x) = x + 7
Step-by-step explanation:
f^-1 = 8(x + 7)
x + 7 = y/8
x = y/8 - 7
f(x) = x/8 - 7
f^-1 = -3(x - 1)
y/-3 = x - 1
x = 1 - y/3
f(x) = 1 - x/3
f^-1 = 4(20 - x)
y/4 = 20 - x
x = 20 - y/4
f(x) = 20 - x/4
f(x) = 20 - 0.25x
f^-1 = x - 7
y = x - 7
x = y + 7
f(x) = x + 7
Answer:
Step-by-step explanation:
In ΔABC,
∠ABC + ∠BAC + ∠BCA = 180 {ANGLE SUM PROPERTY OF TRIANGLE}
41 + 102 + ∠BCA = 180
143 + ∠BCA = 180
∠BCA = 180 - 143
∠BCA = 37
∠CAE = ∠BCA {Alternate interior angles are equal}
x = 37°
