Answer:
A) 0.9(sin50)
Step-by-step explanation:
Since this is a right triangle, we can use
sin a = opposite side/ hypotenuse
sin 50 = x /.9
Multiply each side by .9
.9 * sin 50 = x/.9 * .9
.9 (sin 50) = x
Try B, but note I’m not sure if right.
X = 9
72 / 8 = 9
8 x 9 = 72
Answer:
The area of the base, B, equals
✔ 21
cm2.
The volume of the prism is
✔ 157 1/2
cm3.

<h3>Given</h3>
- PQ = QR . . . . . . Q is the midpoint of PR
- PQ = 3x+14
- QR = 7x-10
<h3>Find</h3>
<h3>Solution</h3>
Put the given expressions in the given relation.
... 3x +14 = 7x -10
Subtract the left side.
... 0 = (7x -10) -(3x +14)
... 0 = (7-3)x +(-10-14) . . . . . simplify
... 0 = 4x -24
Divide by the coefficient of x.
... 0 = x - 6
Add the opposite of the constant.
... 6 = x
The value of x is 6.
