Answer:34a
Step-by-step explanation:
because 6a-4=2a
4a+28=32a
2a+32a=34a
Solve each equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x=-1, -7
If one angle is 80 degrees we can assume that each other angle must be 80, 100, and 100 degrees.
make a line going straight from (0,0) to (2,2) and so on and the other line starts at (0,0) and go to (1,1) and follow along the other line
Answer:
both sides are congruent meaning it is a 45/45 triangle. that makes y=45. you can then use sin(45)=x/12 which when solved is 8.49 approximately
