Answer:

10 degrees

Step-by-step explanation:

First off complementary angles require the sum of both adjacent angles to equal 90 degrees. You are already given the degrees of one of the adjacent angles so all you need to do is a geometric proof. 90 = 80 + x and subtract 80 from each side to get 10 = x.

Answer: I would say that x = 10 degrees

Step-by-step explanation:

The angle has a square, meaning it is a right angle. Right angles are 90 degrees, and you're given 80 degrees + x.

90 - 80 = 10

Hope this helps!

The perimeter of the triangle shown is 412 meters. Find the length of each side.
Fudgin [204]

Answer:

x meters= 35

5x meters= 175

6x - 8 = 202

Step-by-step explanation:

x + 5x + (6x - 8)= 412

12x - 8= 412

12x = 412 + 8

12x = 420

x= 35

5x = 35× 5

= 175

6x - 8= 6(35) - 8

= 210 - 8

= 202

Jake and Gloria are running on the track team. Gloria can run twice as many miles as
Tanzania [10]

Answer:

J+2J=12 so 3J=12 so J=4

Step-by-step explanation:

Use J to represent Jake's miles.

We know that Gloria's miles (G) is twice J, so G=2J

We also know that Jake and Gloria together ran 12 miles.

So we know, J+2J=12 or 3J=12   meaning J=4

So Jake runs 4 miles, and since Gloria is two times that she ran 8 miles.
