Answer:
x = 8
Step-by-step explanation:
For this question, you can use power of a point, more specifically when two secants intersect in the interior of a circle. From this, you get the equation:
(7 + x)(12) = (10)(2x + 2)
You can simplify and solve:
84 + 12x = 20x + 20
84 = 8x + 20
64 = 8x
x = 8
Multiply 3 and 8 then you will have your answer
Because x was *3 you had to y*3 which is
y=6
Triangle A is an Isosceles
Triangle B is Equilateral
Triangle C is Scalene
U have to put a number between it
131,132,133,134,135,136,137,138,139
