What is the value of y?
A) 130°
B) 65°
C) 50°
D) 25°

65

Step-by-step explanation:

130 + the top angle of he triangle  = 180 (bc they make a straight line)

that would mean the top angle is 50

all triangles interior angles add up to 180

180 - 50 = 130

since there are two Ys 130/2 = 65

each y = 65

1/8 3/16 3/4

step-by-step explanation:

you put them as all the same denominator and multiply

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
