Set up the equation
Then you want to het the x variable by itself, by elimating 18. So, you add 18 to both sides
Then to get x by itself you divide by -4 from both sides
You are correct.
Answer:
60°
Step-by-step explanation:
All side are equal, Sum of all angle in traingle is 180
180/3 = 60
Answer:
See attachment.
If altitude = 45 then
side = 2 * height (or altitude) / square root of 3
side = 2 * 45 / 1.7320508076
side = 90 / 1.7320508076
side = 51.9615242271
