Answer:

We know angle y = 78 degrees

Step-by-step explanation:

y and 78 are alternate exterior angles.  Alternate exterior angles are equal if the lines are parallel. AB is parallel to CD  so y = 78

<h3>Answer: y = 78</h3>

==================================

Justification #1: Angle x is 78 degrees as these two angles are corresponding angles (congruent due to the parallel lines). We also know that y = x because they are vertical angles. So by the transitive property, y = 78

Justification #2: The parallel lines mean that the alternate exterior angles are congruent, so y = 78 through one step (instead of multiple steps in the prior justification)

Leona spent 5/8 of 2/3 of her allowance on magazines. What fractions of her total allowance did she spend on magazines? What fra
Olegator [25]

Answer:

7x/12

Step-by-step explanation:

Let her entire allowance be represented by 'x'

She spent 5/8 of 2/3 of her allowance on magazines.

= 5/8×2/3

= 10/24

= 5/12

That 5/12 of 'x'

5/12x

Since her total allowance is x

She will be left with = x - 5/12x

x/1 - 5/12x

12x-5x/12x

= 7x/12

Hence she will be left with 7x/12

A rectangle school banner has a length of 44 inches, a perimeter of 156 inches , and an area of 1496 square inches. The cheerlea
Andrej [43]
Based on the lengths, the cheerleaders' banner is scaled down by a factor of 4.

So, 44 ÷ 4 = 11.

For the perimeter, 156 ÷ 4 is 39.

For the area, you have to do A=bh
(Area = base × height)

The base (length) is 11 inches, multiply that by two to get 22 inches which is the amount for both lengths. If the total perimeter is 39, you have to subtract 22 from that to get the remaining inches which is 17.
17÷2= 8.5 inches. The height is 8.5.

Now you can plug them in
A=bh
A=(11)(8.5)
A=93.5 in^2

The final answer is:
Area = 93.5 in^2
Length = 11 in
Perimeter = 39 in

I hope that helps!

Side JL is 4√2  recall that in a 30-60-90 right triangle the hypotenuse is 2 times the size of the short leg.

JL also serves as the hypotenuse of the 45-45-90 triangle JML.  The ratio of side lengths in this triangle is 1:1:√2

So we can see that the value of x = 4
