Three times the sum of eight and a number is sixty

1 answer:

6 0

If three times the sum of eight and a number is sixty, then you need to break it down to write it out. First, we know we're multiplying 3 * (times) something. That something is 8 and a number, or x. So it'd be 8 + x. So we have 3 * (8 + x). And we know that equals 60, so we have 3 * (8 + x) = 60

Answer:

The last one $(x=11.3, y=8)$ .

Step-by-step explanation:

1) There are three trigonometric ratios for right-angled triangles.

$sin()=\frac{opposite}{hypotenuse}\\cos()=\frac{adjacent}{hypotenuse}\\tan()=\frac{opposite}{adjacent}$

In a right triangle, the hypotenuse, h, is the side opposite the right angle. Relative to the acute angle θ, check the attachment, the legs are called the opposite side, o, and the adjacent side a.

2) In this case, we are given a length and an angle to find x and y.

Let's find x first. To find x we need to use $sin()=\frac{opposite}{hypotenuse}$ .
