Answer:
160
Step-by-step explanation:
The measure of an arc is always twice the degree of the corresponding angle inside the circle. For example, the measure of arc DC is just double the measure of angle DOC; angle DOC is 44 degrees, so arc DC must be 88 degrees.
Angle COB is 80 degrees, so arc CB is 160 degrees.
Answer:
its B
Step-by-step explanation:
Answer:
5x - 2y = - 2
Step-by-step explanation:
Given the 2 equations
- 2x + y = 0 → (1)
- 7x + 3y = 2 → (2)
Subtracting (2) from (1) term by term
- 2x - (- 7x) + y - 3y = 0 - 2, that is
- 2x + 7x - 2y = - 2
5x - 2y = - 2
I'm guessing you mean which equation Equals -9
In each equation you are needing to get rid of X so you divide on both sides
A) -45=5x
-45/5=x
-9=x
and I double checked to make sure nothing else equaled -9 so Your answer Is A
Hope this helped!
Answer:
let us first take a look at the values of the trigonometric ratios given in the question so that we get quite clear about what is to be done.
here ,
now ,
we just have to plug in the values considering certain other things given in the question and we're done!
so let's start ~
hence , proved ~
