Step-by-step explanation:

P=2(L+W), we are given a side of 20 and a side of b

P=2(20+b)

P=40+2b

A) P(6)=40+12=52ft TRUE

B) P(8)=40+16=56ft TRUE

C) P(10)=40+20=60ft FALSE

D) P(12)=40+24=64ft FALSE

E) P(11)=40+22=62ft FALSE

So only A and B are true

Csc is equal to 1/sin

Sin= opposite/hypotenuse

So just take the inverse of what sine would be

Sin= 3/5

So Csc=5/3 :)

Subtitute the pair (3,28) to x and y, if the result in right side is -8, then the pair is a solution to the equation

2x - y/2
= 2(3) - 28/2
= 6 - 14
= -8

The result is -8, so the pair (3,28) is a solution

What type of triangle is defined by the following set of side lengths

NARA [144]

Answer:

ACUTE TRIANGLE 

Step-by-step explanation:

If the sum of the squares of the two shorter sides of a triangle is greater than the square of the longest side, the triangle is acute. However, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse.

Therefore, the triangle with sides 11, 9, and 7 is an acute triangle since 9² + 7² is greater than 11²

${9}^{2} \: + \: {7}^{2} > \: {11}^{2} \\ 130 > 121$
