Solve the Triangle

• 37.8

• 69.3

• 80.6

• 91.3

In the diagram shown of right triangle BAC, m

Draw it out: In the accompanying diagram of right triangle ABC, b = 40 centimeters, m < A = 60, and m < C = 90. Which trig ratio could help you find the length of side a?

• sin(90) = 30/c

• tan(60) = a/40

• cos(30) = a/c

• sin(60) = a/c

Side c, the missing side of this triangle, is the:

• short leg

• long leg

• medium leg

• hypotenuse

Remember the rule: The triangle inequality rule states that the length of a side of a triangle is _______ than the sum of the lengths of the other two sides and ________ than the difference of the lengths of the other two sides.

• less; greater

• greater; less

• equal; greater

• less; equal

Draw it out: If the length of each leg of an isosceles triangle is 17 and the base is 16, the length of the altitude is

• 8

• 8.5

• 15

The sum of the angles in a triangle always equals

• 90

• 180

• 270

• can't be determined
