Answer:

x =12

Step-by-step explanation:

Since this is an isosceles triangle the angles at the bases of the equal sides are equal

The unmarked angle is 4x

The 3 angles of a triangle total 180 degrees

4x+4x+ 84 =180

Combine like terms

8x +84 = 180

Subtract 84 from each side

8x +84-84 = 180 -84

8x =96

Divide by 8

8x/8 = 96/8

x =12

Amy's penny bank is 1/2 full. After she adds 360 pennies, it is 5/6 full. How many pennies can Amy's bank hold?
stellarik [79]

Answer:

1,080 Pennies

Step-by-step explanation:

This question is fairly simple, you just have to simplify it. You are starting at already half-full, so you can keep that 1/2 in mind. Then, she adds 360 pennies to get 5/6. If you convert 1/2 into 3/6, you can see that 360 pennies fills 2/6 of the piggy bank. So now you can solve two different ways. The first, you can take 360 and multiply it by 3 to get the amount that can fit in the piggy bank, because 2 * 3 = 6 and that would make it 6/6, or 1. The other way would be to divide 360 by 2 to get 1/6 of the piggy bank, or 180. Then you can multiply 180 by 6 to get the entire amount.

Hope this helped ^-^
