Question

What is m wtv in degrees

Answer 1

We have been given image of a circle. We are asked to find the measure of angle WTV.

We know that measure of an inscribed angle is half the measure of intercepted arc.

We can see that angle WTV is inscribed angle to arc WV. So measure of angle WTV will be half the measure of arc WV.

`\angle WTV=(1)/(2)\widehat{WV}`

`\angle WTV=(1)/(2)\cdot 90^(\circ)`

`\angle WTV=45^(\circ)`

Therefore, the measure of angle WTV is 45 degrees and 2nd option is the correct choice.
