Question

An isosceles triangle with angles b and c having the same measure is shown. Find the measure of each angle whose degree measure is represented with variables. A= x+ 7y+41,B= 2y+13,C=6x+15

Answer 1

A+B+C =180

7x+49+5y=180 ---> 7x+5y=131

7(15) +49+5(15)=180
180=180

(15)+7(15)+41=A
161=A

2(15)+13=B
43=B

B=C
43=C

A=161
B=43
C=43
