Answer:
x = 6
Step-by-step explanation:
• ∠THX and ∠XHV have a common side HX and a common vertex H
This means they are two adjacent angles.
Then
m∠THX + m∠XHV = m∠THV
Then
53 + 12x−9 = 16x + 20
<u>Solving the equation</u>:
53 + 12x−9 = 16x + 20
⇔ (53 − 9) + 12x = 16x + 20
⇔ 44 = 16x - 12x+ 20
⇔ 44 - 20 = 4x
⇔ 24 = 4x

Answer:

Step-by-step explanation:

The surface area, SA, of a rectangular prism is given by the formula:
SA = 2ab + 2bc + 2ac,
where, a, b, and c are lengths of the 3 sides of the rectangular prism
For this problem, the surface area of the rectangular prism was given to be 208 cm². The two sides given can be assigned the variables, a = 2 cm and b = 10 cm. This leaves us with one side, c, as the unknown dimension. The resulting equation is as follows:
208 cm² = 2(2 cm)(10 cm) + 2(10 cm)(c) + 2(2 cm)(c)
c = 7 cm
The answer is -4 because the number keeps getting divided by -3
