Answer:

23.6°

Step-by-step explanation:

In this question we have to use some trigonometry to work out angle XVW. Since we are working out angles all of the trigonometric functions will have to be to the ⁻¹. The first thing we need to identify is will formula will we use out of the following:

Sin⁻¹ = Opposite ÷ Hypotenuse

Tan⁻¹ = Opposite ÷ Adjacent

Cos⁻¹ = Adjacent ÷ Hypotenuse

-------------------------------------------------------------------------------------------------------

10 = Hypotenuse

4 = Opposite

-------------------------------------------------------------------------------------------------------

We know which formula to use because the length won't be in the triangle for example we will be using the Sin triangle because we don't have an adjacent. If we don't have an adjacent then the other formula's won't work.

Now we substitute in the values to find the value of angle XVW

Sin⁻¹ = Opposite ÷ Hypotenuse

Sin⁻¹ = 4 ÷ 10

The value of angle XVW is 23.57817848

The sum of the two digits of a number is 16. The number formed by reversing the digits is 18 more than the original number. Dete
nydimaria [60]
9u-9t=18

original no. is 10t+u
reversed no. is 10u+t

so its (10u+t)-(10t+u)=18
which gives 9u-9t=18

Can someone please explain y=mx+b
lana [24]

y=mx+b is slope-intercept form, which is a way of writing an equation for a line.

In this equation, m represents the slope and b represents the y-intercept.

x and y are the coordinates of a point on the resulting line.

Here are some examples:

y=3x+2

y=-2x-4

y=8x-1

y=-7x+5

Your food costs are 2250. Your total food sales are 25000. What percent of your food sales do the food costs represent?
liberstina [14]
To get this percentage, divide costs by total food sales

2250 / 25000 = 0.09

then multiply by 100 to get the % = 9%
