Arc PR is 140 degrees because angle Q is the inscribed angle of arc Pr so arc PR is double angle Q and if you add all the sides of the triangle and subtract it from 180 then double angle Q to find arc PR.

It would be X=12 or -12, because when a number positive or negative is inside the absolute value sign it becomes positive. So 12 - 5 is 7

Answer:

$d=60ft$

Step-by-step explanation:

From the question we are told that:

Height $h= 30ft$

Angle $\theta=30 \textdegree$

Generally the equation for Distance traveled is mathematically given by

Since

Distance traveled forms the hypotenuse of a right angle triangle

Therefore

$d=\frac{h}{sin30}$

$d=\frac{30}{sin30}$

$d=60ft$
