Answer:
x = 25 , y = 19
Step-by-step explanation:
Since the triangle has 3 congruent sides then it is equilateral
The 3 angles are also congruent, with each angle = 60° , then
2x + 10 = 60 ( subtract 10 from both sides )
2x = 50 ( divide both sides by 2 )
x = 25
and
3y + 3 = 60 ( subtract 3 from both sides )
3y = 57 ( divide both sides by 3 )
y = 19
Answer:
x = 66
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
I attached your answer below...
For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have
As for the literal part, you can factor 
because it's the power of s with the smallest denominator. So, we have
