Answer: 10
<u>Step-by-step explanation:</u>
First, find m∠C by using the Triangle Sum Theorem:
∠A + ∠B + ∠C = 180°
110 + 43 + ∠C = 180°
153 + ∠C = 180°
∠C = 27°
Next, Use the Law of Sines to solve for c:
$30 = 75%, so divide it by three and you got your 25%, which ia $10.
$10 * 4 = $40.
So the answer is $40.
Hope this helps.
I believe it should be 1.4 since the answer you get is 1.4112903226... you would round but on the tenths place 1.4
Because it was reflected across the x axis, the distance between the two points is twice the distance of the old point from the x axis, and the distance from the old point from the x axis equals the distance from the new point to the x axis. The distance from the x axis is the absolute value of the x=y value. 7.5 is the y value, meaning the point is 7.5 units away from y=0, the x axis. The new point is twice this from the old point. 7.5 x 2 = 15. The new point is 15 units away from the old point.
