Little help please? and thank you

Answer:

45.7

Step-by-step explanation:

Hello there!

We can calculate the missing angle using trigonometry

here are the trigonometric ratios

sin = opposite over hypotenuse

cos = adjacent over hypotenuse

tan = opposite over adjacent

We are given x's opposite side length (8) and x's adjacent side length (7.8)

we are given the information to use the trigonometric ratio tangent

so now we create an equation (remember tan - opposite over tangent)

$tan(x)=\frac{8}{7.8}$

now we solve for x

$\frac{8}{7} =1.025641026$

we're left with

$tan(x) =1.025641026$

finally we want to get rid of the tan

To do so we take the inverse of tan (arctan^-1) and apply it to each side

$arctan^-^1tan(x)=x\\arctan^-^1(1.025641026)=45.7252243$

so x = 45.7252243

finally we round to the nearest tenth and get that the answer is

45.7

Do 3/7 and 7/3 represent the same length on s number line? Explain please

Nitella [24]

No because if you were to make 7/3 a mixed fraction, it would be 2 and 1/3. Thus, they are different lengths on the number line
