Answer:

X is 22.5°

Step-by-step explanation:

» Let's assume our diagram is as above, from trigonometric ratio:

${ \tt{ \red{ \sin( \theta) = \frac{opposite}{hypotenuse} }}} \\$

theta is X
opposite is a
hypotenuse is c

${ \tt{ \sin(x) = \frac{a}{c} }} \\ \\ { \tt{ \sin(x) = \frac{5.7}{14.9} }} \\ \\ { \tt{ \sin(x) = 0.3826}} \\ \\ { \tt{x = { \sin }^{ - 1}(0.3826) }} \\ \\ { \boxed{ \tt{x = 22.5 \degree}}}$

NEED HELP ASAP!!! ALGEBRA 1 STUFF (20pts.)

It's not actually 20 pts it's 10 pts if you send a question and you want 20 pts off it would be 10 for other ppl. like

10pts off = 5
20pts off = 10
30pts off = 15

and so on so it's like counting by 5's each time you lose points

Yan is climbing down a ladder. Each time he descends four rungs on the ladder, he stops to see how much farther he has to go

anastassius [24]

Question:

Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?

4+4+4+4

8+8+8+8

(-1)(4+4+4+4)

(-8) + (-8) + (-8) + (-8)

Answer:

$Total = (-8) +(-8) +(-8) +(-8)$

Step-by-step explanation:

Given

$Rungs = -4$ --- It is negative because he is climbing down

$Steps = 8$

Required

An expression for the number of rungs climbed

To do this, we simply multiply the number of rungs by the steps taken.

$Total = Rungs * Steps$

$Total = -4 * 8$

This can be rewritten as:

$Total = -8 * 4$

The product, when written as sum is:

$Total = (-8) +(-8) +(-8) +(-8)$

I need help with this math problem!!

Vesnalui [34]

In order to find which one is or isn't, you need to solve for the value of 'x'.
2x + 15 = 35
2x = 20
x = 10

Substitute x =10, into equation. If each side are not the same (i.e. 0=2), then that's the equation that is not equivalent,

Answer is B
Double check this. Chur! :)

Hope this makes sense.
