Find the lengths of g, h, and j. Round answers to the nearest tenth. (marking brainliest for correct)
Bezzdna [24]

Answer:

j=13, g=20.8, h=24

Step-by-step explanation:

The overall shape given and the shape within, are both right triangles. With right triangles, you are allowed to use the pythagorean theorem formula (a^{2} + b^{2} = c^{2}) in order to solve for some sides. In this case, that would be j and h. The five in the smaller triangle is represented by b and the 12 is the hypotenuse so it is represented by c. When you plug in those numbers in the pythagorean theorem formula, you will find the value of j to be 13. When looking at this, we see that 12 is the second greatest value in the right triangle values that we just found, so we know the the opposing angle for that one will be 60 degrees. The 5's opposing side is therefore 30 degrees. When subtracting 90 and 30, we get 60, so therefore you can use the 30 60 90 formula to find the sides of the bigger triangle. The 60 degrees represents g. This formula will be a\sqrt{3}. The a is 12 since it is the smallest value. So therefore, g is 12\sqrt{3}, which is 20.8. Now that we have this side, we can just use the pythagorean theorem formula to find the remaining side. Therefore, h is going to be 24

A rectangle has a perimeter of 30. It is dilated by a scale factor of 2.
LuckyWell [14K]

Answer:

It is 60.

Step-by-step explanation:

When shapes are dilated (when they get bigger or smaller), perimeter changes linearly—in direct proportion with length. This means if the scale factor is 2, then you multiply it by 2. 2 multiplied by 30 equals 60.

7. 4 = 8X + 5Y _____________________________
Strike441 [17]

As the equation does not consists like terms we can only get x , y equations.

Step-by-step explanation:

Firstly, they are not like terms.

If the value to be is found is X then,

8x+5y=4

Now subtract 5y on both sides

8x+5y-5y=4-5y

here both positive 5y and negative 5y get cancelled

Now divide by 8

x=(4-5y)/8

If we need y value then,

subtracting both sides by 8x

5y=4-8x

Now dividing with 5 on both sides

y=(4-8x)/5  =>y=4/5 -8x/5

According to Y=mx+c

slope = m = 4/5

y-intercept = -8x/5.
