Answer:

3/10

Step-by-step explanation:

Subtract the sum of 1/3, 4/15 and 1/10 from 1:

                                 10/30 + 8/30 + 3/30 = 21/30, or 7/10

                                   Then:  1 - 7/10 = 3/10

Help me please number 7 (please show work)
astra-53 [7]

Answer:

m<H=30 degrees by the Triangle Sum Theorem, so <H=<V. <G=<U, they are right angles. If GH=UV, triangle FGH=triangle TUV by the ASA.

x=3  and y=8

Step-by-step explanation:

H equals 30 by 180-150=30 (getting 150 by adding 60 and 90)

I know this is not much of a answer, but I hope it helps a little.
