Answer:
- 10
- 46
- 2
- -21
- -10
- -4
Step-by-step explanation:
Put the numbers where the letters are and do the arithmetic.
h - g = 3 - (-7) = 3 + 7 = 10
g² - h = (-7)² -3 = 49 -3 = 46
g + h² = -7 +3² = -7 +9 = 2
gh = (-7)(3) = -21
g - h = -7 -3 = -10
g + h = -7 +3 = -4
X=11 is the answer right?
We use the Pythagorean theorem here, because we have the two sides and a right angle between them, so we calculate the hypotenuse like this:
x^2 = 6^2 + 8^2
x^2 = 36 + 64
x^2 = 100
x = square root of 100
x = 10
The correct answer is B.10.
Hey there! I"m happy to help!
The interior angles of a triangle add up to 180. We have 2 angles that have a value of x, so 2x+138=180.
We subtract 138 from both sides.
2x=42
We divide both sides by 2
x=21.
Have a wonderful day! :D
