Find A, B, and C Help ASAP! {10 points up}
1 answer:
so we have a 60-30-90 triangle (top one)
so since we know 6 is x (the side on the right angle and 60 degrees)
b is 2x or 2(6) = 12
a is x√3 = 6√3
for C I need to use a 45 45 90 triangle
Since b is 12 and its x√2 to find x we should write it as
x√2 = 12
√2 √2 divide by √2
x = 12/√2 but we must rationalize the denominator
12/√2 times √2/√2 = 12√2/2 and that's c

Answer:
Step-by-step explanation:
When the graph crosses the x axis value of the graph is zero
Therefore 6x2-11x-10=0
6x2-15x+4x-10=0
3x(2x-5)+2(2x-5)=0
(3x+2)(2x-5)=0
So, it shows that 3x+2=0 and 2x-5=0
x= and x=2.5
x intercepts are (,0) and (2.5,0)
When x=0
y=6x2-11x-10 = 0 - 0 -10 = -10
y intercepts in (0, -10)
