Answer:

115

Step-by-step explanation:

To find the missing angle all you have to do is add the 2 nonadjacent interior angles which are 75 and 40 to get the exterior angle which is 115.

Hope this helps!:)

75+40+x=180

X= 65

65 + x= 180

Answer is 115°

In a spelling bee, Anish's placement is both the 11th highest and the 25th lowest among all the spellers who participated. How m

Vlad [161]

Answer: There are 35 spellers participated in the spelling bee.

Step-by-step explanation:

Since we have given that

Rank of Anish's placement at the highest = 11 th

Rank of Anish's placement at the lowest = 25 th

We need to find the number of spellers participated in the spelling bee.

So, Number of spellers participated in the spelling bee is given by

Highest + Lowest - 1

= 11 + 25 - 1

= 36 - 1

= 35

Hence, there are 35 spellers participated in the spelling bee.

Which of the following is a perfect square trinomial?

shutvik [7]

Answer:

Step-by-step explanation:

Take a look at what happens when squaring either of these...

$(ax-by)^2=(ax-by)(ax-by)=a^2x^2-2abxy+b^2y^2\\\\(ax+by)^2=(ax+by)(ax+by)=a^2x^2+2abxy+b^2y^2\\$

Notice a couple of patterns.

1. The last term has a positive coefficient. That rules out answer choices C and D.

2. The coefficient of the middle term is either $+2ab \text{ or } -2ab$ . So what are a and b? a is the square root of the x^2 term and b is the square root of the y^2 term.

$25x^2 \Rightarrow a=5\\\\9y^2 \Rightarrow b=3\\\\ab=15\\\\2ab=30$

The middle coefficient needs to be either +30 or -30. The answer is choice A.
