What is the sixth triangular number?

Triangular numbers are numbers that are formed from the sum 1+2+3+4... The equation for the nth triangle number is (n2+n)/2 In this case, we want the sixth triangle number, so feed this into the equation: (62+6)/2 =(36+6)/2 =42/2 =21 Thus the sixth triangle number is 21.


What is the length of side c in Triangle ABC to the nearest whole number if A equals 42 degrees and B equals 87 degrees and a equals 24?

28 The Law of Sines: a/sin A = b/sin B = c/sin C 24/sin 42˚ = c/sin (180˚ - 42˚ - 87˚) since there are 180˚ in a triangle. 24/sin 42˚ = c/sin 51˚ c = 24(sin 51˚)/sin 42˚ ≈ 28


If two of a triangle's angles measure 42 degrees and 48 degrees how would you classify that triangle?

It's important to remember that a triangle's angles will always total 180 degrees. 180 - 42 - 48 = 90. The last angle is 90 degrees, so this is a right triangle.

The 110 degree angle makes this triangle an obtuse triangle.


If a triangle has an area of forty two square inches and a base of six inches what is its height?

Formula: Area of triangle= 1/2 * base * height Therefore 42 (area of triangle) = 1/2 * 6 (base) * height 42 = 3 * height 42/3 = (3 * height)/3 14 = height Therefore, the height of triangle is 14 inches
