Answer:
<h3>The answer is option D</h3>
Step-by-step explanation:
Since it's a right angled triangle we can use trigonometric ratios to find the value of y
To find the value of y we use tan

We have the final answer as
<h3>18.61</h3>
Hope this is helps you
1. {2x−3y=9
{3x+5y=4
2. {(2x−3y=9)×5
{(3x+5y=4)x3
3. {10x-15y=45
{9x+15y=12
4. (10x-15y=45) + (9x+15y=12)= (19x=57)
5. (19x=57)÷19
6. x=3
7. 2(3)-3y=9
8. 6-3y=9
9. -3y=9-6
10. (-3y=3)÷(-3)
11. y=-1
Answer: x=3 and y=-1
Answer:
B
Step-by-step explanation:
Cos(0)=1
since the diagram shows x as (1,0)
Of course, they are not equivalent.
One has an extra π in the equation.
