How do you find the missing angle of a triangle when all other angles are there?

1 answer:

7 0

All angles in a triangle add up to 180 degrees. So, if you are missing an angle, add up the degrees of the angles present and subtract that from 180. That will be the value of the missing angle in degrees.

In the system of equations below, I want to eliminate the variable y.

Mekhanik [1.2K]

Answer:

(x,y)=(-1,1)

Step-by-step explanation:

Given that,

3x + 5y = 2 .....(1)

6x - 10y = -16 ....(2)

Finding the value of x from equation (1).

$x=\dfrac{2-5y}{3}$

Put the value of x in equation (2)

$6(\dfrac{2-5y}{3}) - 10y = -16\\\\2(2-5y)-10y=-16\\\\4-10y-10y=-16\\\\-20y=-16-4\\\\y=1$

Put the value of y in equation (1) :

$3x + 5(1) = 2\\\\3x=2-5\\\\3x=-3\\\\x=-1$

So, the solution of the equations is (-1,1).

100% 110,200,000

If 110.2 million households equals 100%, then you just cross multiply to solve for what households are 17.7% - which is 19,505,400.
