Answer:
25.5
Step-by-step explanation:
first find angle E.
remember, all angles in a triangle always add up to 180 degrees.
E = 180 - 90 - 20 = 70 degrees
now we use the law of sines.
ED/sin(20) = DC/sin(70) = EC/sin(D)
EC = x
sin(D) = sin(90) = 1
24/sin(70) = x/1 = x
x = 25.5
Answer:
14. -g + 10, 15. 12k + 3
Step-by-step explanation:
I'm assuming you want to simplify the equation. For 14, we distribute -2. This gets us -2g + 10 + g. We can simplify that to -g + 10. We can't simplify that, so our answer is complete. For 15, we combine 8k and 4k to get 12k + 3. That can't be simplified, so we are done.
117, just add the two and subtract from 180
