Answer: option C
Step-by-step explanation:
The diagram of the triangle is shown in the attached photo. The triangle is a right angle triangle ABC
Assuming the given angle is #,
Recalling the trigonometric ratio,
tan # = opposite / adjacent
If tan # = 4, it means
opposite / adjacent = 4/1
Therefore, opposite = 4 and adjacent = 1
Applying Pythagoras theorem,
Hypotenuse^2 = opposite ^2 + adjacent ^2
Hypotenuse = AC
Opposite = 4
Adjacent = 1
AC^2 = 4^2 + 1^2 = 17
AC = ± √17
To determine cos #, we would apply another trigonometric ratio,
Cos# = adjacent /hypotenuse
Cos# = 1/±√17
Cos # =-1 /√17 or 1/√17

Step-by-step explanation:
All real numbers since there is no exclusions. (-inf, inf)
Answer:
C. 4
Step-by-step explanation:
<u>Use the slope formula:</u>

m = the slope.
<u>Substitute the values into the formula:</u>

<u>Solve:</u>

<u>Simplify 16/4:</u>

Y=mx +b
So
10-7y=0
-7y=-10+0 Y= -10/-7 Y= 10/7
Your y-int. Is 10/7
