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
Answer:
9
Solution:
Write it in an algebraic form (x is your number)
2x-11=7
Now solve
2x=7+11=18
X=18/2=9
Answer:
y=1/4x-4
Step-by-step explanation:
slope is 1/4 and the y intercept is -4
your answer is c 29. To figure this out take 59-180= 121. Then add 121 and 30 =151. next subtract 151 from 180 and you get C 29
120 degrees I hope you’re helping
