If you have the adjacent angle and hypotenuse, will you use SINE, COSINE or TANGENT
COSINE
1 of 7
If the hypotenuse is equal to 10cm and one of the other sides is equal to 6cm, what is length of the last side?
10^2 - 6^2 = 64, square root of 64 is 8, last side = 8cm
2 of 7
The bearing from A to B is 312 degrees, the angle from ABC is 48 degrees, what is the ANGLE ACB?
180 - 48 - 48 = 84 (angles in triangle add to 180
3 of 7
The bearing from A to B is 312 degrees, the Angle ABC is 48 degrees, what type of triangle is ABC?
Triangle ABC is an isosceles triangle (base isos angles are equal)
4 of 7
If the opposite side is 10cm and the adjacent side is 8cm, what is the angle? (Use calculator)
tan-1(o/a || 10/8) = angle, angle = 51.3 degrees

What is the acronym for finding angles in a triangle?
SOH CAH TOA (Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent)

What is "Pythagoras Theorem"?
a(squared) + b(squared) = c(squared)
