Ok, so we know that RST is equal to 6x+12
And RST is also equal to 78 + 3x-12
so we set them equal to each other
6x + 12 = 3x - 12 + 78
And simplify
3x = 54
x = 18
Finally, we solve for the angle with 18 for x
6(18) + 12
108 + 12
120
Hope this helps
I think that the answer for that one is A
Answer:
Step-by-step explanation:
y=sqrt(x-7)+3 is a transformed from the parent function y=sqrt(x) by the following:
right 7 units
up 3 units
I think it is either 4.41 or 1.84 Sq Ft
y = 3x - 4 answer x = 11/3
4x + 3y = 1 answer -3/4y + 1/4
2-3x = y answer -1/3y + 2/3
