What is the distance BC between the two horizontal parallel bars?
pochemuha
One thing you should notice is that the transverse line and the parallel line form a right triangle. We are told that the base is 4 and the angle between the hypotenuse and the leg is 45°

From this we can solve for the second leg. Here's the list of trig functions

sinФ = opposite/hypotenuse
cosФ = adjacent/hypotenuse
tanФ = opposite/adjacent

Since we are only given the adjacent and we are trying to solve for the opposite leg, we can deduce we use tanФ. So we get

tan45 = x/4

Multiply by 4 to isolate x and we get

4*tan45 = x

Graph the inequality x plus y is equal to or greater than -4
Setler [38]

Answer:

Step-by-step explanation:

x+y≥-4

consider x+y=-4

when x=0,y=-4

point is (0,-4)

when y=0,x=-4

point is (-4,0)

draw a line through (0,-4) and (-4,0)

put x=0,y=0

0+0≥-4

which is true.

Hence origin lies on the graph.

graph is on and right of the line.
