20/2.54=7.87401575
7.87401575/12
0.65616798 feet
We know that y =-2x.
To find the value of x when y = -16, we simply plug -16 in for y in our equation.
y = -2x
-16 = -2x Divide both sides by -2, to get x all by itself
8 = x
Answer is A
Answer:
C. 172.5 ft²
Step-by-step explanation:
area of triangular roof piece is 1/2(10)(6.9) = 34.5
there are 5 of them so 34.5 x 5 = 172.5 ft²
Answer:
congruent angles just have the same measurement, no matter what the degree is.
complementary angles are = to 90 degrees
supplementary angles are = to 180 degrees
Answer:
(9, 13, 22)
Step-by-step explanation:
We can use the triangle inequality theorem to help us solve this problem. We know that the two shortest sides of a traingle added up (their sum) needs to always be greater than the longest side of the triangle. Taking that information, we can figure out that 9+13=22. 22=22, not 22>22. This means that is the right answer, hopefully that helps!
