Triangle ABC and triangle DCE are congruent, so line DE = line AB
Use the cosine rule to find angle ACB






Angle ACB = 48.1°
If you are solving for x than the answer would be x=4.
Answer:
60
Step-by-step explanation:
1/3 of 60 is 20
in other words
20 x 3 = 60
First make an equation for first tree
Y=2x+50
Then second tree
Y=1x+59
Then put them equal to eachother
2x+50=1x+59
Solve by subtracting 1x and then subtracting 50
Answer= x=9
