Answer:
x =5.1
Step-by-step explanation:
For the angle 82, we know the adjacent side and the opposite side
tan 82 = opposite/ adjacent
tan 82 = 36/x
Multiply by x on each side
x tan 82 = 36/x*x
x tan 82 =36
Divide by tan 82
x tan 82/ tan 82 = 36 / tan 82
x = 36/ tan 82
x=5.059470049
To the nearest tenth
x =5.1
Answer:
x = ± 2
Step-by-step explanation:
Given
f(x) = x² + 1 and (x, 5 ) is a solution then f(x) = 5
Equating the two gives
x² + 1 = 5 ( subtract 1 from both sides )
x² = 4 ( take the square root of both sides )
x = ± = ± 2
Thus (- 2, 5) and (2, 5) are solutions
