An angle measure 87°. What is the measure of its supplement?

93 degrees

Step-by-step explanation:

Since supplementary angles are two angles that, when added together, equal a sum of 180 degrees, all you need to do is subtract the given angle (87) from 180. 180 - 87 = 93 degrees!

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
