Answer:
a and b are positive
Step-by-step explanation:
We are given that


We have to find that a and b are positive or negative.
We have

It means b is positive and greater than 4.

Adding 3 on both sides



Hence, a is positive and greater than 4.
Therefore, a and b are positive
7x+y-9=0
move constant to the left by adding its opposite to both sides. the sum of the two =0
Answer:
10
Step-by-step explanation:
We will use trigonometry to solve this problem.
We see that the side provided is the hypotenuse and the side we are looking for is opposite to the angle provided. Thus, we will use sin since sin uses opposite/hypotenuse.
Now we solve.
sin45 = x/14
sin45 * 14 = x
x = 9.899494936611665
