Answer:
C
Step-by-step explanation:
Angle 1 and angle 4 sit on the same straight line which means
<1 + <4 = 180
We are given that <4 = 105 degrees. So the equation above becomes.
<1 + 105 = 180 Subtract 105 from both sides
<1 = 180 - 105
<1 = 75
Answer:
66 inches
Step-by-step explanation:
v² = 55² + 26² - 2(55)(26) · cos 103°
v² = 3025 + 676 - [2860 · cos 103°]
v² = 3701 - (-643.4)
v² = 4344.4
v = ≈ 66
88 and -88. are absolute values and opposite integers
0.80
9 in 0.79 is the tenth place. Since 9>5, upon rounding up 0.79 to the nearest tenth, 0.80 would be the answer.
The dealer paid 'C' for it. He decided to sell it for 10% more than C .
That would be (1.10 C) , and that's the $856.90 .
So the equation is . . . 1.10 C = $856.90
Divide each side by 1.10 : C = $856.90 / 1.10
<em>C = $779</em>
