Answer:
9) QR = 4.0
10) AC = 4.1
Step-by-step explanation:
Tan = Opps. / Adj.
9)
Tan(60) = 7 / QR
QR = 7 / Tan(60)
QR = 7 / 1.732
QR = 4.0415
QR = 4.0
10)
Tan (27) = AC / 8
AC = Tan(27) * 8
AC = 0.5095 * 8
AC = 4.076
AC = 4.1
Answer : D
Formula for height is
H = SA / (2 x 3.14 x r) - r
I can’t see A-c can u take another picture

4[2y + -3] + -1 = 11
Reorder the terms:
4[-3 + 2y] + -1 = 11
[-3 * 4 + 2y * 4] + -1 = 11
[-12 + 8y] + -1 = 11
Reorder the terms:
-12 + -1 + 8y = 11
Combine like terms: -12 + -1 = -13
-13 + 8y = 11
Solving
-13 + 8y = 11
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '13' to each side of the equation.
-13 + 13 + 8y = 11 + 13
Combine like terms: -13 + 13 = 0
0 + 8y = 11 + 13
8y = 11 + 13
Combine like terms: 11 + 13 = 24
8y = 24
Divide each side by '8'.
y = 3
Simplifying
y = 3</span>
