Answer:
Angles BCF and EFH
Step-by-step explanation:
When two parallel lines are crossed by another line (the transversal), the angles in matching corners are called corresponding angles. DCF and GFC isn't the correct answer because those would be vertical angles. GFC and BCA would not be corresponding because they do not fall in matching corners. And same with EFH and BCA. Therefore, BCF and EFH would be corresponding.
B. 1/4(n - 64)
Multiplying n and -64 by 1/4 leaves you with 1/4n - 16, the original equation.
One hundred fifty three thousand
x+6 is x+6. It's an expression. Not sure what you need help with.
The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
