What is the value of x?

Got answer its 8

x = 80°

Step-by-step explanation:

To solve this we just need to know that the sum of the inner sides of a triangle will always give us 180 °

from here we only have to apply a simple formula by adding the sides of the triangle and knowing that the result is 180 and from there clear the value x that we need to find out

70 + 30 + x = 180

x = 180 -30 - 70

x = 80°

i do not know the answer

step-by-step explanation:

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
