Just subtract.
33-15
its 18
so 18 points
36°, 72°, 72°
let x be the third angle then each of the other 2 angles is 2x
the sum of the angles in a triangle = 180° thus
x + 2x + 2x = 180
5x = 180 ( divide both sides by 5 )
x = 
= 36
the angles are 36°, 72° and 72°
16 divided by 1
is 16 with remainder 0
= 16 R 0
= 16 0/1
For this you will have to know how to add fractions. First of all i like to add the whole numbers together first, so 2+2+3= 7. so now what you have to do is add the fractions together. so 2/3 + 1/4 + 1/2 = ? you will have to find a common denominator for 3, 4, and 2; which is 12. Multiply each fraction by the needed number to get each denominator to 12. so 2/3 will be multiplied by 4, 1/4 will be multiplied by 3, and 1/2 will be multiplied by 6. The new equation and answer will be: 8/12 + 3/12 + 6/12 = 17/12. 17/12 as a mixed fraction is 1 5/12. now we add 1 5/12 and 7 to equal 8 5/12. and then you will have to subtract this from 10, using common denominators and such to get your final answer of 2 1/12. (sorry for the long spiel on how to do this question)
A..Just plus it if not wrong
