Answer:
c.
Step-by-step explanation:
a negative fraction is lower than a positive.
So its negative, then positive, then the biggest fraction, which is 3/2.
If you need more clarification, please let me know :)
If it is a right triangle, then a^2 + b^2 = c^2
6^2 + 8^2 = 100^2
36 + 64 = 100
100 = 100
Yes, the triangle is a right triangle.
Hope this helps =)
I would go with C. like the other person
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
2sinxcosy = sin(x + y) + sin(x - y) , then
with x = 70 and y = 20
2sin70cos20
= sin(70 + 20) + sin(70 - 20)
= sin90 + sin50
= right side , thus proven
