I'm gonna go with triangle B. Triangles A,C,and E all look to be somewhat congruent in that they're all equilateral. Triangle D and F look similar but Triangle b looks like its isosceles and the others aren't like that.
Answer:
l and 3, 2 and 4, 5 and 11, 8 and 16
Step-by-step explanation:
you would put the one over 3 then 2 over 4 then 5 over 11 then 8 over 16 then put it in a equation and solve
I got 18 and 30 for my answer
Answer:
sin(a) =
Step-by-step explanation:
cos(2a) = cos²(a)-sin²(a) = [1-sin²(a)]-sin²(a)= 1 - 2sin²(a)
1 - 2sin²(a) = -20/29
- 2sin²(a) = -49/40
sin²(a) = 49/80
sin(a) =
sin(a) = =
sin(a) =
