Answer:
Step-by-step explanation:
The sum of the angle measures of a triangle is 180°. Find the value of x . Then find the angle measures of the triangle.
find the value of x
x + 2x + x + 8 = 180
4x = 180 - 8
4x = 172
x = 172 : 4
x = 43
find angles
2x = 43 * 2
2x = 86°
-------
x = 43°
--------
x + 8 = 43 + 8
x = 51°
-----------------------
check
86 + 43 + 51 = 180°
the answer is good
In this question , we have to find the postulate that is illustrated for the real numbers

The postulate is Additive inverse postulate which states that

Where a is the real number and -a is the opposite of a. It states that , if opposite of a number is added with the number, the result is 0 .
The answer to the question is y=-24x
Range= 4
Range is the highest number minus the lowest number, 10-6=4
Answer:
28.3
Step-by-step explanation:
Use the Pythagorean Theorem to solve for the answer. 10^2 + x^2 = 30^2
