How to use the Pythagorean Theorem

Snowcat [4.5K]

a²+ b² = c² is the formula for pythagorean theorem.

it is used to find out the hypotenuse(the side opposite the 90° angle) of a right angled triangle.

the two sides adjacent to the 90° angles are 'a' and 'c'. the theory is that if you add the squares of a and b, the hypotenuse is equal to c².

How do you do these kind of problems? could someone please provide me steps?

DerKrebs [107]

1/5×m+2/3-2=m-2/5
Multiply both sides by 15:
3m+10-30=15m-6
12m=14
m=14/12
m=1.16

What is -2 1/2 + 1 1/3 in fraction form?

olga nikolaevna [1]

$-2\frac{1}{2} +1\frac{1}{3}=\frac{-1}{6}$

Solution:

Given expression is $-2\frac{1}{2} +1\frac{1}{3}$ .

Let us first convert mixed fraction into improper fraction.

$-2\frac{1}{2} +1\frac{1}{3}=\frac{(-2\times 2) +1}{2} +\frac{(1\times 3) + 1}{3}$

$=\frac{-4 +1}{2} +\frac{3 + 1}{3}$

$=\frac{-3}{2} +\frac{4}{3}$

Take LCM for the denominators (LCM of 2, 3 = 6) and make the same.

$=\frac{-3\times3}{2\times3} +\frac{4\times2}{3\times2}$

$=\frac{-9}{6} +\frac{8}{6}$

$=\frac{-1}{6}$

$-2\frac{1}{2} +1\frac{1}{3}=\frac{-1}{6}$

Hence the fraction form of $-2\frac{1}{2} +1\frac{1}{3}$ is $\frac{-1}{6}$ .
