So you would take your 90° angle which is the box on the bottom right hand corner and add 40° which would equal 130° and then you would subtract 180° -130° and you would get 50°.

What is 3/4- (-5 1/4) =<br><br> NEED HELP ASAP

Fantom [35]

Answer:

Step-by-step explanation:

$\frac{3}{4} - (-5\frac{1}{4})$

-5 1/4 is a mixed fraction. so we convert it into improper fraction

$-5\frac{1}{4}=-\frac{5*4 +1}{4}=-\frac{21}{4}$

$\frac{3}{4} - (-\frac{21}{4})$

negative and negative becomes positive

$\frac{3}{4} +\frac{21}{4}$

Both fractions have same denominators. so we can combine the numerators

$\frac{3+21}{4}=\frac{24}{4}$

Divide the fraction

$\frac{24}{4}=6$
