Answer:

53°

Step-by-step explanation:

Complementary angle = 90°

So, 12° + (x+25°) = 90°

Subtract 12 from both sides

x+25°=78°

Subtract 25 from both sides

x=53°

Answer:

x=43

Step-by-step explanation:

complementary angles will add up to equal 90 so we set up an equation to solve x

12+x+25=90

step 1 combine like terms

12+25=37 so now its

37+x=90

step 2 we subtract each side by 37

90-37=43

x=43

hope this helps and have a great day :)

Simplify: 18q2−45q+25/9q2−25.
Svet_ta [14]

Answer:

\frac{(6q-5)}{(3q+5)}

Step-by-step explanation:

Given: \frac{18q^{2}-45q+25 }{9q^{2}-25 }

Factorizing the numerator and the denominator, we have:

18q^{2} - 45q + 25 = 18q^{2} - 30q - 15q + 25

                         = (3q - 5)(6q - 5)

and

9q^{2} - 25 = (3q - 5)(3q + 5)

So that,

\frac{18q^{2}-45q+25 }{9q^{2}-25 } = \frac{(3q-5)(6q-5)}{(3q-5)(3q+5)}

                 = \frac{(6q-5)}{(3q+5)}

Therefore,

\frac{18q^{2}-45q+25 }{9q^{2}-25 } = \frac{(6q-5)}{(3q+5)}
