The answer is C) m∠1 + m∠2 = 90
Explanation: So ∠1 is x and ∠2 is x-4
Basically you know than ∠3 is 90° ... And a straight line is 180° .. So technically we can just find out 180-90 is 90(the other angle 1 + 2).
To get 90° we'll add ∠1 and ∠2 in other ways, like technical thinking-
So you already know adding ∠1 and ∠2 is 90°. So ∠1 + ∠2 = 90°
In other words you can say m∠1 + m∠2 = 90
I think it is 22, but I did it in my head so i might be way off
What you do is you “take apart” the net so it has individual rectangles, then you multiply the 2 sides... you do that for each rectangle then add it all up
Find the Greatest Common Factor (GCF)
GCF = 5
Factor out the GCF (Write the GCF first, and then in parenthesis, divide each term by the GCF.)
5(5x/5 + 15/5)
Simplify each term in parenthesis
<u>5(x + 3) </u>
10^4 = 10,000
9 x 10,000 = 90,000
