In order for two triangles to be considered as similar, they must be
- equiangular (all angles equal)
- all sides equal (sss)
- if two pairs of two sides are in proportion or are matching, and one included angle is equal
Q4a) yes, because all the angles are equal (equiangular)
b) yes, because all sides are in matching ratio (so 10/5 is 2, 6/3 is 2 and 8/4 is 2; so they are in matching ratios)
c) yes, because if you plus 60 and 70, you get 130. Minus 180 and 130, you get 50. So, in both triangles the angles will be 60,70 and 50; so they're equiangular
Answer:
37.5
Step-by-step explanation:
You would do 25 divided by two in order to find out what the distant in one inch is. 25 divided by two is 12.5. Then, you do 12.5 multiplied by 3.
The negative of it would be the positive so the answer is 1/4
Answer:
VX = 4n +7
explanation:
the equation is VX = n + 7 + 3n, all you need to do is add the n variables and get VX = 4n + 7.
Treat it just like and equation at first. Multiply the 10 on both sides to get rid of it, leaving you with 50 
x. Then on the number line, since there is a line under it, you would make a filled in circle and an arrow pointing towards 51 and beyond
