ABC is an equilateral triangle, solve for both x and y

x=16 and y=5

Step-by-step explanation:

Set each side equal to 49, so 3x+1=49 and 18y-41=49. For the first equation, subtract 1 on both sides to get 3x=48, then divide both sides by 3 to get 16. For the second equation, add 41 to both sides to get 18y=90. Divide both sides by 90 to get 5.

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
