Mathematics
1 answer:
butalik [34]3 years ago
3 0

Answer:

9

Step-by-step explanation:

If the sine of an angle is equal to the cosine of an angle, that means that the sides adjacent and opposite to that angle are equal. One triangle that has two equal sides is an isosceles triangle. We can set this triangle to be a 45-45-90 degree triangle, which means that the angle would be 45.

Now, we have to find the value of

4\tan^2(45)

and

5\tan(45)

The tangent of 45 is 1, so 1 squared times 4 is 4.

We have 4\tan^2(45) = 4.

Again, the tangent of 45 is 1, and 1 times 5 is 5.

We have 5\tan(45) = 5

5 + 4 = 9

vitfil [10]

The correct representation of the scale is 1 inch:2 feet

<h3>What are scale ratios?</h3>

Scale ratios are used to show the relationship between quantities of different measurements

The scale is given as:

1 inch = 2 feet

Represent the above scale, as ratio

Ratio = 1\ inch:2\ feet

Hence, the correct representation of the scale is 1 inch:2 feet

A fountain is made up of two semicircles and a quarter circle. Find the perimeter of the fountain. Round answers to nearest tent
AlexFokin [52]

Answer:

39.275

Step-by-step explanation:

the diameter of the semicircle is 10

A semicircle is half a circle, and a quarter circle is 1/4 of a circle.

Perimeter of a semicircle is ¶d/2

= 3.142 x 10/2 = 3.142 x 5 = 15.71

For 2 semicircles that will be 15.71 x 2 = 31.42

For the quarter circle, perimeter is ¶d/4 = 3.142 x 10/4 = 3.142 x 2.5 = 7.855

Total perimeter = 31.42 + 7.855 = 39.275
