Find the value of x in the triangle shown below.<br> Choose 1 answer:
Ad libitum [116K]

For the triangle, x is 12 units long.

Step-by-step explanation:

Step 1:

According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

The hypotenuse is the side which is the longest in the triangle and is always opposite the right angle.

In the given triangle, the hypotenuse is 13 units long. The other two sides measure 5 units and x units.

Step 2:

By substituting the known values, we get

13^{2} = 5^{2} + x^{2} .

x^{2} = 169 - 25 = 144.

x = 12.

Rounding this off to the nearest hundred, we get that x is 12 units long.

Jenny washed dishes 4 times as many as her brother last month. Her brother washed dishes 8 times. Jenny said she could multiply
Julli [10]

Jenny is incorrect in her calculation.

For every time that Jenny's brother washed dishes, Jenny washed dishes 4 times. This tells that the the times they washed dishes occur in the ratio 4 :1. If Jenny's brother washed dishes 8 times, Jenny has to have washed dishes 4\times 8=32 times. The way Jenny's is doing the calculation implies that his brother washed dishes 3*\times 8 =24 times. He calculation yields a wrong result.
