Answer:

x = 24

obtuse isosceles triangle

Step-by-step explanation:

x = 24 because a triangle has to have all the angles add up to 180. So x + x +132 = 180.

180-132 = 2x

48 = 2x

x = 24

It is an isosceles because two of the angles are the same and one is different which means two of the sides are the same and one is different. (isosceles = icicle is how I remember it). Obtuse because there is an angle that is over 90 degrees.

x=24

Which of the q-values satisfy the following inequality?

6 - 3q ≤ 1

(Select all that apply)

q = 0

q = 1

q = 2

Answers

Answer:

q = 2

Step-by-step explanation:

simply plug in q as the numbers listed. examples:

6 - 3(0) ≤ 1

6 - 0 ≤ 1

6 ≤ 1

not true. 6 is greater than 1. asking for less than or equal to 1.

6 - 3(1) ≤ 1

6 - 3 ≤ 1

3 ≤ 1

not true, 3 is greater than 1. asking for less than or equal to 1.

6 - 3(2) ≤ 1

6 - 6 ≤ 1

0 ≤ 1

true. 0 is less than 1.

q=0,1,2 all are valid values for the given inequality.

What is an inequality?

An inequality is an inequation separated by <,>≥,≤. The relationship between two values that are not equal is defined by inequalities. Inequality means not equal. Generally, if two values are not equal, we use “not equal symbol (≠)”.

Given here: The inequality 6-3q≤1

 Now simplifying the inequality

6-3q≤1

Substracting by -3 on both sides we get

6-3q-6≤1-6

-3q≤-5

Now multiplying both sides by -1/3 we get

q≥-5/3

or q≥-1.666

Therefore q=0, q=1,q=2 all satisfy the inequality q≥-5/3

Hence, q=0,1,2 all satisfy the inequality and they are all valid values.
