Answer: a = 3.5

Step-by-step explanation:

14=4a

divide both sides by 4

14/4 = 3.5

4a/4 =1a or a

so a= 3.5

If the sin of angle x is 4 over 5 and the triangle was dilated to be two times as big as the original, what would be the value o
beks73 [17]

Answer:

Sin of x does not change

Step-by-step explanation:

Whenever a triangle is dilated, the angle remains the same as well as the ratio for sides of triangle. For smshapes with dimensions, when shapes are dilated the dimensions has increment with common factor.

From trigonometry,

Sin(x)=opposite/hypotenose

Where x=4/5

Sin(4/5)= opposite/hypotenose

But we were given the scale factor of 2 which means the dilation is to two times big.

Then we have

Sin(x)=(2×opposite)/(2×hypotenose)

Then,if we divide by 2 the numerator and denominator we still have

Sin(x)=opposite/hypotenose

Which means the two in numerator and denominator is cancelled out.

Then we still have the same sin of x. as sin(4/5)

Hence,Sin of x does not change

How do you solve -1x+20 is greater than -7+35
rusak2 [61]

\huge\fbox{Hello~there!}

Let's solve this inequality!

\rm{-x+20>-7+35

What can we do to solve this inequality? Well, first of all, we can add -7 and 35:

\rm{-x+20>28

Now, move 20 to the right, using the opposite operation:

\rm{-x>28-20

Subtract:

\rm{-x>8

Divide both sides by -1 to isolate x:

\rm{x (Answer)

_____________

<em>Additional comment</em>

When we divide both sides of an inequality by a negative number, we flip the inequality sign.

____________

I hope you find it helpful.

Feel free to ask if you have any questions.
