Your answer would be D. It is one-half the area of a rectangle with sides 4 units x 3 units. This is how you solve these problems. You have to draw a rectangle around the triangle Think about it, It wouldnt be double the surrounding rectangle and the dimentions are 3 x 4, not 4 x 4.
Hope I was most help to you!
Answer:
The measure of the arc DAC is 240°
Step-by-step explanation:
we know that
The semi-inscribed angle is half that of the arc it comprises.
so
m∠RDC=(1/2)[arc DAC]
we have
m∠RDC=120°
substitute
120°=(1/2)[arc DAC]
240°=[arc DAC]
Rewrite
arc DAC=240°
The second one, and the two last should be the right answer,
Hope this helped:)
