Answer:
3=11
Step-by-step explanation:
Start of by doing -2-1
x = - 6 and x = 7
given x² - x - 42 = 0 ← quadratic in standard form
(x - 7 )(x + 6) = 0 ← in factored form
equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 6 = 0 ⇒ x = - 6
I really hope that helps cause I went all out and best of wishes!!
The angle here is an acute angle at ground level. Then the side adjacent to this angle is 126 feet. The opp. side is the tower, 111 feet tall.
Then
tan theta = opp / adj = 111 / 126. Using the inverse tangent function, we find that the measure of the angle is 0.722 radian or 41 degrees (to the nearest degree).
