"<span>two angles are complementary;" that means the sum of two angles is 90. Since the sum of all three is 180, the last angle is 90. It is a right triangle.
"</span><span>two angles have equal measure;" we can't have two angles which are 90, so the other two are equal. But they sum to 90, so what number plus itself is 90? 45+45=90. We know now that the triangle has measures 45, 45, and 90.
We know that the legs of the triangle are the same, so we can use the Pythagorean theorem to show that </span>
, where h is the length of the hypotenuse and l is the length of the legs.
Of course, this means
. But "<span>the shortest side is half the length of the longest side</span>"! No triangles like this exist.
The only true statement is D

She needs to buy 6 bags of soil. the correct option is B
Given
Caisha has a circular garden with a radius of 4 ft.
She needs to put a layer of soil on top. e
Each bag of soil covers 9.42 square feet.
<h3>What is the radius of a circular garden?</h3>The radius of the circular garden is equal to the pie times of the square of the radius.
The radius of the circular garden is;
Therefore,
The number of bags of soil will she need to buy is;
Hence, she needs to buy 6 bags of soil.
