3sqrt(2)

You can either use Pythagorean theorem or special triangle proportions to find the side that is parallel to z. Since in a 45-45-90 degree triangle, the hypotenuse is the leg times the square root of 2, and the hypotenuse is 3, we know that the leg is 3/sqrt(2) which is equal to 3 sqrt(2) / 2. Since z is twice this length, we know that z is equal to 2 x 3sqrt(2)/2 = 3sqrt(2)

Isolating a variable in two equations is easiest when one of them has a coefficient 1.
Tomtit [17]

Answer:

Option C.

Step-by-step explanation:

The given equations are

3A-B=5

2A+3B=-4

We need  isolate one of the variables, such that it appears by itself on one side of the equation.

Isolating a variable in two equations is easiest when one of them has a coefficient 1.

In equation 1, coefficient of B is 1. So, we can easily isolate one of the variables.

The equation is

3A-B=5

Subtract 3A from both sides.

-B=5-3A

Multiply both sides by -1.

B=3A-5

Therefore, the correct option is C.

X = 55, because 60 + 65 = 125 and 180 - 125 = 55
Lina20 [59]

Answer: x= 55 because 60 + 65 =125 and 180 - 125 = 55

Step-by-step explanation:

The sum of three angles in any triangle is 180. Therefore you add the two angles that you have and use that number to subtract it by 180. Then you will have your answer. Also you can get the answer to y by subtracting the value of x from 180.
