3° and 177°
supplementary angles sum to 180°
let x be an angle then the other angle is 59x
x + 59x = 180
60x = 180 ( divide both sides by 60 )
x =
= 3
the angles are 3° and (59 × 3 )= 177°
Answer: A.12
Step-by-step explanation: Cause we have to subtract because let see 48+12=60 so we have to subtract each numbers with 12.
Exercise 1:
The exponents are wrong: when you divide two power, you subtract the exponents:

Exercise 2:
The function represents a growth rate of 300%! 3% is actually written as 0.03, so the correct function is

Exercise 3:
To factor a quadratic equation, we have to find the roots. Once you have the roots
, you can factor the expression as 
In this case, the solutions are
, which yields the factorization

Exercise 4:
When you multiply two powers of the same base, you add the exponents:

So, in your case, you have

Answer:
The answer is 7.
Step-by-step explanation:
7*1.49=10.45
5*1.99=9.95
10.45+9.95=20.38
