Answer:

169 cm²

Step-by-step explanation:

Recall that the area of the largest square is |PR|²

Also recall from Pythagoras Theorem that:

|PQ|² +|QR|² =|PR|² ---->1

Also we have that the sum of the areas of the three squares is 338 square centimeters.

This implies that:

|PQ|² +|QR|² +|PR|²=338---->2

Put equation (1) into (2)

|PR|²+|PR|²=338

Simplify to get:

2|PR|²=338

Divide both sides by 2 to get:

|PR|²=338

|PR|²=169

Answer:

All answers are in explanation

Step-by-step explanation:

Based on the graph, which inequality is correct for a number that is to the right of -3? A number line is shown from negative 8
scZoUnD [109]

We have been given a number line graph. Using that graph, we have to identify about which inequality is correct for a number that is to the right of -

The entire portion of the number line to the right of negative 3 is shaded that means variable x must be greater than 3. So we may use x>3 or x>=3

A circle is shown at negative 3 which means 3 is not the part of answer so we will use x>3 not x>=3


Hence final answer is x>3

PLEASE HELP ME I NEED TO KNOW THE ANSWER TO THIS QUESTION!!
Angelina_Jolie [31]
I would say 115

because the angles should add up to 180 
so if you take 65 away from 180 = 115

that and its an obtuse angle so it need to be more than 90 but less than 180.

115 is my best guess
