A) Using the special right triangle ratio for 30-60-90 triangles (which is 1-√3-2, opposite sides of the angles respectively, we can find that the side opposite the sixty degree angle is 41√3.
b) The hypotenuse is the same. Using the ratios, we see that the hypotenuse is 82.
c)sin(30)= opp/hyp = 41/82 = 1/2
cos(30)= adj/hyp = 41√3/82 = √3/2
tan(30)= opp/adj = 41/41√3 = 1/√3 = √3/3
Answer:
C.) -7/5
Step-by-step explanation:
To subtract fractions, we need to have common denominators. So first, we will change -1 1/5 to -6/5.
Now we will change the denominator of both -6/5 and 1/2 to 10.
We now have:
5/10 and -12/10
5-12=-7
So the answer would be -7/5
If we want to use the number line, we would first find 5/10 (1/2) on the graph and count down (to simulate subtraction) 12 units since we are subtracting by 12. :))
57.8
Step-by-step explanation:
To get the answer we have to find 15% of 68 and then subtract it from 68$
15% its 0.15
0.15*68=10.2
68-10.2=57.8 - its the answer
Common ratio = 6/3 = 2
10th term
= 3(2)^(10-1)
= 3 x 2^9
= 3 x 512
= 1536
