Isn't it B because if y was squared, y^2, and the quotient of 28 and 7 was decreased from it, then wouldn't it look like the expression of B? (This is because the quotient of 28 and 7 is represented by 28/7, because fractions actually mean to divide). I hope this helps! (But I'm a 6th grader, so at least I hope someone agrees with me!) :D

Please help me solve for angle B!!

Vaselesa [24]

I believe it is 50 degrees

Explanation:

180-115 = 65 degrees

Since the base angles of of an isosceles triangle are equal,

Angle C =angle A= 65 degrees

65 times 2 = 130

180-130=50

50 degrees=measure of angle B

Hope this helps
