The semi circle and isosceles triangle have the same base AB and the same area. Find angle x. Show workout.

Nina [5.8K]

$r= \frac{AB}{2} \\ \\A_{semi\:circle }=\frac{r^2\pi}{2} \\ \\A_{triangle}=A_{semi\:circle }=\frac{r^2\pi}{2} \\ \\A_{triangle}= \frac{2r\times h}{2} =rh \\ \\\frac{r^2\pi}{2}= rh \\ \\h=\frac{r\pi}{2} \\ \\ \tan{x}= \frac{h}{r} = \frac{\frac{r\pi}{2}}{r} =\frac{\pi}{2} \\ \\x=\arctan{\frac{\pi}{2}}
\\
\\x \approx 57.52^o$

First we will go to the section that lists that students that like hotdogs. 76 students out of 150 like hotdogs. Out of those 76 students, which of them like burgers?
32 students like hotdogs and burgers. 32/76 is equal to .421..., which when multiplied by 100 is equal to approximately 42.1%. We found the conditional frequency, or the column frequency. The correct answer is C.
