If the sum of two angles is 200 grade and their difference is 20 degree. Find the angle?
Answers
Step-by-step explanation:
Formulate an equation to solve for this one.
- I did x+x-20= 200
x represents the larger angle between the two triangles.
x-20 represents the smaller triangle which the problem states is 20 degrees smaller.
- if you solve the equation I gave you above you will get your answer. x= 110
your angles should be 110 and 90. You can check by adding those numbers which will equal to 200.
Hope this helps!

call the larger triangle abc
then the smaller triangle cde is similar to abc (all angles are equal, aaa).
ab is the side that is 36, and we wish to find de, the side corresponding to ab
area_cde = area_abc - area_cde --> area_abc / area_cde = 2
let x=length of de
ratio of areas = (ratio of sides)^2
