x = 6
Find the area of a triangle with a base of 10 and a height of 6
Solution = 30
Area = 1/2(b x h)
1/2(10 x 6) = 30
In a right triangle, opposite = 3, hypotenuse = 5
find sinθ.
Solution:
sinθ = 3/5
Find the slope between (1,2) and (3,6).
Solution: 2
m = (y2 - y1) / (x2 - x1)
m = (6 - 2) /( 3 - 1) = 4/2 = 2
Solution = 5
(2+4+6+8 )/4 = 5
Solve: x2 - 9 = 0 (Simplify)
Solution:
x2 = 9
x = ±3
A right triangle has legs 6 and 8. Find the hypotenuse.
Solution: 10
a2 + b2 = c2
62 + 82 = 100
c = √100
c = 10
Find tanθ if opposite = 8 and adjacent = 4. (simplify solution)
Solution: 2
tanθ = 8/4 = 2

Vertex = (0,0)
What is the probability of drawing a heart from a standard deck? Simplify
(A standard deck contains 52 cards, with an equal number of hearts, spades, diamonds, and clubs)
Solutiuon: 1/4
P = 13/52 = 1/4
Solve: x2 - 5x + 6 = 0
(Write solutions as a whole number or fractions)
Solution:
factor: (x - 2)(x - 3) = 0
x = 2,3
Solution = 4√(2)
d = √ [(x2 - x1)2+ (y2 - y1)2]
d = √[ (6 - 2)2 + (7-3)2 ]
d = √(32)
d = 4√(2)
Find sin(30°) = ? 
Solution = 1/2
sin(30°) = 1/2
Solve f(x) = x2 - 4 for f(x) = 0
Solution: 2, -2
x2 - 4 = 0
x = 2, -2
