Answer:
C. between 3.5 and 4
Step-by-step explanation:
We are given


Since, we have to solve for x
so, firstly we will set them equal

we can multiply both sides by x
and we get

now, we can use graphing calculator
and find intersection point between y1 and y2
so, we can see that
x=3.538 lies between 3.5 and 4
so,
C. between 3.5 and 4
Multiply 5/7 by 2 to get 10/14.

Answer:
50 degrees
Step-by-step explanation:
x + y = 90
x = 2y - 30
2y - 30 + y = 90
3y - 30 = 90
3y = 90 + 30
3y = 120
y = 120/3
y = 40
x = 2y - 30
x = 2(40) - 30
x = 80 - 30
x = 50 <====== angle x
