Hi, We know:
Sin(a + b) = 2.Sin(a).Sin(b)
Then,
= 2Sin(a).Cos(b)/Cos(a).Cos(b)
Canceling Cos(b)
= 2Sin(a)/Cos(a)
As Tan(a) = Sin(a)/Cos(a)
Then we will stay:
= 2Tan(a)
Or
= Tan(a) + Tan(a)
There is anything wrong on the alternatives
Answer:
Step-by-step explanation:
you got this i believe in you!
1) either you'll get a negative number
Or
2) You'll get a positive Number..
But I'm guess you'll get a positive number
Answer:
See below ~
Step-by-step explanation:
<u>Finding x-intercept</u>
- Take y = 0
- 2x - 5(0) = 10
- 2x = 10
- x = 5
- x-intercept is at (5, 0)
<u>Finding y-intercept</u>
- Take x = 0
- 2(0) - 5y = 10
- -5y = 10
- y = -2
- y-intercept is at (0, -2)
