Answer:
first is 20 second is 40 third is 60 and last is 80
Step-by-step explanation:
Answer:
The answer is 90
Step-by-step explanation:
It is B because the equation for slope is x/y and when x=1 y=2 so it is 1/2
For the first image can you give us the choices for each one?
1/sin^2x-1/tan^2x=
1/sin^2x-1/ (sin^2x/cos^2x)<<sin tan= sin/cos>>
= 1/sin^2x- cos^2x / sin^2x
= (1- cos^2x) / sin^2x <<combining into a single fraction>>
sin^2 x / sin^2x <<since 1- cos^2 x sin^2 x
=1
this simplifies to 1.
