Answer:
d
Step-by-step explanation:
I think it’d be 2 but I’m not really sure
• y is vertically opposite to the one whose measure is 43º.
So,
y = 43º.
• x and y are supplementary angles:
x + y = 180º
x = 180º <span>– y
x = 180º </span><span>– 43º
x = 137</span><span>º.
</span><span>• z and x are vertically opposites.
So,
z = x
z = 137º<span> <</span></span>——<span><span>— this is the answer.</span>
I hope this helps. =)

Given.
Radius of the Half sphere is 3 inches.
From the figure;
Radius of half sphere= Radius of cylinder= Radius of cone=3inches
Height of cone= 4inches.
Height of cylinder=6inches.
Volume of cone=(πr²h)/3
=(π3²×4)/3
=(12π) inch³
volume of cylinder= πr²h=π3²6=54π inch³
Volume of half sphere= (4/3) π r³=π(4×3³)/3 (1/2)=π×4×9/2=18π inch³
Total area of Composite figure=(12π +54π +18π) inch³
=84π inch³
=(84)× 22/7inch³
=12×22 inch³
=264inch³
Hope it helps...
