The answer is k = 15. A straight line is 180 degrees. L to Y is a ray which is a line. And M to X is a straight line. So the interior angle Y is the same as 4k+5 as well as 6k+10.
So your equation would look like this...

180=115+4k+5

180=120+4k
-120 -120

60=4k

60/4= 4k/4

15=k

Three numbers have absolute values of 2,4 and 9. The product of all the numbers is positive.
Margaret [11]
The absolute value of a number is how far away it is from 0 on a number line.
Example) 2 is two numbers away from 0, but neg. 2 (-2) is also two numbers away from 0

So basically. A positive number has the absolute value of itself. (2= a value of 2) and negative numbers have the absolute value of the positive form of that number. (-9= a value of 9)

Numbers that have the absolute value of 2: 2 and -2
Numbers that have the absolute value of 4: 4 and -4
Numbers that have the absolute value of 9: 9 and -9

You are looking to add your numbers together to make a positive.

So the answer is the positive answers to the absolute values: 2,4,9

2+4+9=15

15 is a positive number.

Can someone help me with this problem
TEA [102]

Answer:

y = 102, z = 67

Step-by-step explanation:

The angles 113 and z form a straight angle and are supplementary, thus

z = 180 - 113 = 67

The sum of the 4 interior angles of a quadrilateral = 360°

Sum the interior angles and equate to 360 for y

y + 102 + 89 + 67 = 360, that is

y + 258 = 360 ( subtract258 from both sides )

y = 102
