Answer: <em>In the upper triangle x = 33° and in the lower triangle x = 128°</em>
Step-by-step explanation:
<em><u>Upper triangle:
</u></em>
<em>x = (180° - 114°) ÷ 2 = 33°</em>
<em><u>Lower triangle:</u></em>
<em>x = 180° - 26° × 2 = 128°</em>
The answer is x=-80.
First subtract 4 from both sides.
-6=
+4
-6-4=+4-4
-10=
Multiply 8 on both sides to isolate x.
-10·8=
-80=x

Answer:
17 seconds
Step-by-step explanation:
h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..
28 = -2t² + 34t + 28
Now solve for t...
0 = -2t² + 34t (subtract 28 from both sides)
0 = t² - 17t (divide both sides by -2)
0 = t(t - 17) (factor out a t)
So
t = 0
or
t - 17 = 0
t = 17
0 seconds is the initial height. At 17 seconds, the ball will return to that height
