Answer:

\frac{1}{6}

Step-by-step explanation:

1/8 ÷ 3/4 is 1/6 because that's as many times it can go into to it and u would have to do keep chang flip

1

\frac{1}{8}  \div  \frac{3}{4}  \\  \frac{1}{8}  \times  \frac{4}{3}  =  \frac{4}{24}  \\  \frac{4}{24}   \div  \frac{4}{4}   =  \frac{1}{6}

I need help fast!!!!!!​
ziro4ka [17]

Answer:

Z= 180 X = 95   y= 147

Step-by-step explanation:

Z=180 because it is a line and when it is a line it = 180 degrees

for X you want to first find the angle of the other triangle and when you do you subtract that # from 180 because those 2 angles make a line

to find that angle next to X is...

180- (the other 2 angles in the triangle)

180- 45- 50

180-95

85 degrees

now do

180-85

95 degrees   -- this is what X =

now you want to find the angle that is left in one triangle

so do

180- 95- 52

180- 147

33 degrees -- the angle that was missing

to find Y do...

180- 33

147 degrees -- this is what Y =
