1/2 x = 20
x = 2 x 20 = 40
Answer:
Alternate Exterior Angles Theorem
Step-by-step explanation:
By looking, we can see that they are exterior angles. Because 2 parallel lines are cut by a transversal, the angles are congruent.
Answer:
x={(y+1) / 5}²
Step-by-step explanation:
y = 5√x +3 -4
⇒y = 5√x -1
add 1 on both sides
⇒ y + 1 = 5√x
divide both sides by 5
⇒(y+1) / 5 = (5√x) /5
⇒(y+1) / 5 = √x
now, square both sides
⇒{(y+1) / 5}² = (√x)²
∴{(y+1) / 5}² = x
