Answer:
72
Step-by-step explanation:
there is 180 degrees in a triangle
Answer:
D) a = - 5/2
Step-by-step explanation:
2x -5y - 7 = 0
5y = 2x - 7
y = 2/5 x - 7
the slope of this line is therefore 2/5 (factor of x).
the perpendicular slope is then (exchange y and x and flip the sign) -5/2, which is then a and the factor of x.
Answer:
2
Step-by-step explanation:
you get 2 because 5 times 2 equals 10 and 6 times 2 equal 12. so you get 10/12
Answer:
nevermind
Step-by-step explanation:
Answer:
AB or x =6sqrt(3) (which is what the pic ask for)
but you ask for AC which is 9
Step-by-step explanation:
The hypotenuse is twice the length of the short leg.
The short leg is 3sqrt(3) (because I see it is opposite the smallest angle which is 30 in this case).
So the hypotenuse is twice 3sqrt(3) which is 6sqrt(3)
You are also asking for AC though... That is the short leg times sqrt(3) so that measurement is 3sqrt(3)*sqrt(3)=3(sqrt(3*3))=3(3)=9
