Answer:
15 i thinkk
Step-by-step explanation:
Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.
Factors of 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 34, 36, 72.
Common factors: 1, 2, 3, 6, 18.
18 is the greatest common factor.
GCF = Greatest common factor.
The value of Tan (a + b) is .
Given as :
Tan b =
Sin a =
∵Sin Ф =
So, =
Now, Base² = Hypotenuse² - Perpendicular²
Or, Base² = 13² - 12²
Or, Base² = 169 - 144
Or, Base² = 25
∴ Base = = 5
And Tan Ф =
Or, Tan a =
Now, Tan (a + b) =
Or, Tan (a + b) =
or, Tan (a + b) =
Hence The value of Tan (a + b) is . Answer
<
3/2
2+1=3
3*3/2=4.5
it would not make sense if it was 2/3 cuz look what u get.......
3*2/3=2
(2,0)
x=2 and y=0
Hope this helps
