The answer to this question is 11.
Answer with step-by-step explanation:
The way the question is worded, this actually shouldn't be correct. The correct answer should be
.
Because the trapezoids are similar, we can find the ratio of their perimeters by actually just finding the ratio of their sides.
Why?
By definition, the corresponding sides of a polygon are in a constant proportion. The perimeter is simply the sum of all sides of the polygon. Since we're just adding the sides, the proportion will still be maintained.
Therefore, we'll just need to ratio of their corresponding sides. The only two corresponding sides that are marked are
and
.
The ratio of
is
.
The reason why it ideally should be
and not
is because the question states
, which mentions
first, so our answer should follow this respective order. I believe you were marked right anyways because the specific order is not specified, but generally, you want to give your answer respectively by default.
Option C: 90° is the value of x.
Explanation:
The given expression is
for 
We need to solve the expression.
Thus, we have,

Subtracting both sides by 4, we have,

Adding both sides by 8 sin x, we get,

Dividing both sides by 10, we have,

Taking
on both sides of the equation, we get,


Thus, the value of x is 90°
Hence, Option C is the correct answer.
Answer:
<h2> 934boxes</h2><h2> 4 trips</h2>
Step-by-step explanation:
Given the total number of books 42,000
Ok, firstly let us calculate the number of boxes required, given that a box can contain 45 books
number of boxes= 42,000/45
number of boxes=933.3 boxes
approximately 934boxes
Also, given that the truck can carry online 250 boxes in one trip
then it must make 934/250= 3.7 trips
approximately the truck will make 4 trips to carry all the boxes
Answer:
B
Step-by-step explanation:
The angle that has tan 5 / 12 is ∠ABC so A is not the answer. The angle that has cos 5 / 13 is ∠BAC so B is the answer.
