100
Write the tangent ratios for angles a and b.
Angle a - Tan o = 8/6
Angle b - Tan o = 6/8
100
What is the probability that I will roll an even number AND then roll an odd number on a six-sided dice?
1/2 * 1/2 = 1/4
100
Are these triangles similar?
No they are not similar
100
What is the angle relationship between e and h?
Alternate interior angles
200
Find y.
Tan 70o = y / 10
y = 27.47
200
What is the probability that I will roll a 3 OR a 6 on a six-sided dice?
1/6 + 1/6 = 1/3
200
Are these triangles similar? If so write the similarity statement.
Yes, by SAS

Find x.
92 + x2 = 142
x = 8.06
300
Find a.
Tan 65o = 24 / a
a = 11.19
300
What is the probability that I will land on yellow AND then a number greater than 2
2/8 * 6/8 = 3/16
300
Are these triangles similar? If so write the similarity statement. Find x
Yes, by AA DEF ABC
6/4 = x/2.4 x = 3.6
300
Find the perimeter.
122 + 52 = x2 , x = 13
Perimeter = 12+13+5 = 30
400
First find the missing angle. Then use that angle to find z.
Angle = 68
Tan 68o = 8 / z z = 3.23
400
What is the probability that it will land on blue OR purple?
3/8 + 2/8 = 5/8
400
Are these triangles similar? If so write the similarity statement. Find x
Yes, by AA. CDB CEA
5/3 = 7/x x = 4.2
400
First find z. Then find the perimeter.
4/6 = x/10 z = 6.67
102 + 6.672 = y2 y = 12.02
perimeter = 10 + 6.67 + 12.02 = 28.69
