Answer:

x = 62

Step-by-step explanation:

If the triangle has two values that are the same like your 6s that means that they have the same angle, so you take the angle(56 degrees) and subtract 180 and 56 making 124. You take 124 and divide it by 2. Making x =62.

HELP ASAP!!! I SUCK AT MATH AND I DON’T understand this!!!

anyanavicka [17]

Answer:

Part A:

$\frac{13}{20}$

Part B:

$\frac{1}{39}$

Step-by-step explanation:

The total number of candies is 40.

10 + 14 + 4 + 12 = 40

14 are Butterfinger and 12 are Crunch.

14 + 12 = 26

$\frac{26}{40}$

$\frac{26}{40}=\frac{26/2}{40/2}=\frac{13}{20}$

$\frac{10}{40} =\frac{10/10}{40/10} =\frac{1}{4}$

40 - 1 = 39

$\frac{4}{39}$

$\frac{1}{4}$ × $\frac{4}{39}$

$\frac{1}{39}$
