It’s C because if you type it In this is what it comes out as
We know that
<span>The measure of the external angle is the semi difference of the arcs that it covers.
so
see the picture attached to better understand the problem
m AB=128</span>°--------> by central angle
<span>m ACB=360</span>°-128°-----> m ACB=232°<span>
</span>∠x=(1/2)*[m ACB-m AB]<span>
</span>∠x=(1/2)*[232-128]-----> ∠x=(1/2)*104°-----> ∠x=52°
<span>
the answer is</span>
∠ x is 52°<span>
</span>
Answer: im good u
Step-by-step explanation:
I really don't know sorry
To find the volume use the volume formula:
V = a²(h/3)
V = 40²(29/3)
V = 1600(9.67)
V = 15,472
The closest to that answer is B. 15,467 cm³
Hope this helps :)
