Answer:

it's 20

Step-by-step explanation:

(X+5)° + (7x-5)° + x°= 180° { sum of the three angles of the triangle is 180°}

X+5+7x-5+X = 180

X+7x+X+5-5= 180

9x+0 = 180

9x = 180

therefore X= 180/9

= 20

All angles are of triangle and thus give sum of 180⁰

x + 5 + 7x - 5 + x = 180⁰

9x = 180⁰

x = 20⁰

Please help ASAP PL u will get 15 points and brainliest
inysia [295]

To be a function each different x value would have a different Y value.

First one is a function, there are no repeated Y values.

The second one is a function.

Third one is not a function because it has two identical Y values with different x values.

The fourth one is a function.
