Answer:
z² = x² + y²
Step-by-step explanation:
Given
z² - y² = x² ( isolate z² by adding y² to both sides )
z² = x² + y²
21% were absent, if you divide 146 by 680 and multiply by 100, then round to the nearest whole number, you get 21
Hello! To find the answer to this, let’s do 6x + 4x = 180. Combine like terms and you get that 10x = 180. Divide each side by 10 in order to get 18. Angle 1 = 108 degrees and Angle 12 = 72 degrees. Odd number angles match each other and even number angles match each other. In this case, 5 has the same angle measurement as 1, which is 108. The answer is D: 108 degrees.
0.88......ones (decimal), tenths, hundredths
so 8 is in the tenths place....8/10
-7x-5y=-47x+9y=-4
combine like terms to cross out the 7x
solve for y, to get -2
plug it back in to one of the equations and x is 2
y=-2
x=2
