Adiya’s method is not correct. To form a perfect square trinomial, the constant must be isolated on one side of the equation. Also, the coefficient of the term with an exponent of 1 on the variable is used to find the constant in the perfect square trinomial. Adiya should first get the 20x term on the same side of the equation as x2. Then she would divide 20 by 2, square it, and add 100 to both sides.
Answer:
19.0
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship ...
Cos = Adjacent/Hypotenuse
cos(38°) = 15/w
w = 15/cos(38°) ≈ 19.035
The length of the missing side is about 19.0.
Answer:
Hello. The answer is 250.
Step-by-step explanation:
The explanation takes alot of time
The two important tips are
Sum of the interior angles of triangle is 180
And for those which have 4 sides are 360
Have you learned PEMDAS? (Parenthesis, exponents, multiplication, division, addition, subtraction). That is what I am going to do here.
The first parenthesis, let's solve. 7*10=70-5=65
The second parentheisis: I am assuming the negative sign is a typo, and this answer will be off if it is not. Sorry. 5*10=50
65*50=3250
I hope this helps, and let me know if you need further assistance.
