Answer:
120
Step-by-step explanation:
you have to find the value so there three angles so you would have to find a number that is timed 3 to equal 360
39 is 65% of 60
65% use a shopping cart.
P = 528
P = a + b + c = 200 + 107 + 221 = 528
The missing side length is 3 units long.
Use the Pythagorean Theorem where c²=a²+b²,
c=2√3, c²=12
a²=√3, a²=3
Solving for the missing side yields a side length of 3.
