I think it’s the one in the top right? cuz the negative would cancel out the 3x then u would have the 7x • 7x aka 7x to the second power
The answer is x=1. I showed my work in the screenshot provided
Answer:
x = 48
Step-by-step explanation:
Substitute -4 for F and do the arithmetic.
.. C = (5/9)*(-4-32) = (5/9)(-36) = -20
-4 °F corresponds to -20 °C.
The value of x in the right triangle is 4 units.
<h3>How to find the side of a right triangle?</h3>
The side x of the right triangle can be found using trigonometric ratios.
Therefore,
sin 30° = opposite / hypotenuse
sin 30 = x / 8
1 / 2 = x /8
cross multiply
8 = 2x
divide both sides by 2
8 / 2 = 2x / 2
x = 4
