Answer:
Step-by-step explanation:
Since B is right angle, AC is hypotenuse as opposite it.
BC is opposite to angle A which is 33°.
<u>We know that:</u>
- sine = opposite / hypotenuse
<u>So we have:</u>
- sin 33° = BC / 7 ⇒ BC = 7 sin 33°
Correct choice is C
Answer:
$94.50
Step-by-step explanation:
At store B, the sales tax rate is 7%, so the tax charged will be 7% of the cost of repair:
0.07 · $1350 = $94.50
Area of a triangle = 1/2 x base x height
Area = 1/2 x 8.7 x 8.6
Area = 37.41 square feet

Answer:
7. d. l = 6.48 cm, w = 6.48 cm
8. d. square
Step-by-step explanation:
For a given area, the perimeter can always be shortened by reducing the length of the long side and increasing the length of the short side. When you get to the point where you can't do that, then you have the minimum perimeter. You will reach that point when the sides are the same length: the rectangle is a square.
__
7. In light of the above, the best dimensions are √42 ≈ 6.48 cm for length and width.
__
8. In light of the above, the shape is a square.
_____
The attached graph shows the length of one side (x) and the associated perimeter. The other side is 42/x, which will also be 6.48.
