Please help with question 3 please math

So because of the way 30-60-90 triangles work, the side opposite to the 30 degrees is half of the side opposite to the 90 degrees. (If u finish the triangle, you’ll see the 30 degrees). So because of this fact, u know that the side opposite to the 90 degrees will be twice as much as 7 yards. This means her height will be 42 feet, which is higher than the tree.

You can also do
sin30 = 21/x
1/2 = 21/x
x = 42
42>40

both graphs increase on their domain

neither graph has a y-intercept

step-by-step explanation:

the following points can be visualized easily from the graph

there is a hike in both the graphs so the graphs are increasing on their domain.x-intercept of log x and log 6x are differentthere is a vertical asymptote of both the graphs so there is no y-interceptas both the graphs are increasing so there is no horizontal asymptote
