B^2 = a^2 - c^2
b^2 = 9^2 - 5^2
b^2 = 56
b = 7.5
Answer:
Step-by-step explanation:
3y=7x+2

one pair is (1,3)
go on adding 3 in x=1,you get corresponding value of y.

Answer:
<A = 35 degrees
Step-by-step explanation:
<A = x
<B = 2x
<C = 2x + 5
X + 2x + 2x + 5 = 180 degrees
5x + 5 = 180
5x = 180 -5
x = 175/5
x = 35
Step-by-step explanation:
Discriminant : k² - 4(12)(27) < 0
So k² - 1296 < 0, -36 < k < 36.
