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:
4/(m-4)^2
Step-by-step explanation:
=(m+2)/(m-4)^2-(m-2)/(m-4)^2
=m+2-m+2/(m-4)^2
= 4/(m-4)^2
This is the correct answer.
55 times 30 is 1650 and 30 times 5 is 150
The answer is 1650 over 150
Hello,
Please, see the attached file.
Thanks.
Answer:
Cos E= 24/25
Step-by-step explanation:
Length of hypotenuse: 7^2+24^2=625. 625 square root=25
Thus, DE is 25.
Sin D= 24/25, so that is false.
Tan D= 24/7, so that is false.
Cos E= 24/25, so that is true
Sin E= 7/25, so that is false.
