Answer:

Step-by-step explanation:
Using the diagram, we can see that the angle is a right angle.
With this information, we can set up an equation:

Please note that right angles are always equivalent to 90 degrees.

Add like terms:

Subtract 82 from both sides:

Divide both sides by 8

Answer:
(3x + 4)° + 50° = 90° (complement angle)
3x° + 4°+ 50° = 90°
3x° +54° = 90°
3x° = 90°- 54°
x° = 36°/3
x° = 12°

H(t)=-16t^2+1221 is the function for the height as a function of time. It will hit the ground when h=0 so:
-16t^2+1221=0
16t^2-1221=0
16t^2=1221
t^2=1221/16
t=√(1221/16) seconds
t≈8.74 seconds (to nearest hundredth of a second)
x - 3y = 1 ⇒ 3x - 9y = 3
3x - 5y = 11 ⇒ 3x + 5y = 11
-14y = -8
-14 -14
y = ⁴/₇
x - 3y = 1
⁴/₇ - 3y = 1
- ⁴/₇ - ⁴/₇
-3y = ³/₇
-3 -3
y = ⁻¹/₇
(x, y) = (⁴/₇, ⁻¹/₇)
Answer:
66.7% = 0.667 in decimal form.
Hope that helps!
