Answer:

x=7

Step-by-step explanation:

The square indicates the angle is a right angle which equals 90°

5x+18+4x+9=90°

5x+4x+18+9=90°

9x+27=90°

9x=90°-27°

9x=63°

Divide both sides by 9

x=7.

Hope you're having a splendiferous day, ever willing to help...

What is 3/4- (-5 1/4) = 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

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