The length of an angle is the reaction of the opposite leg length to the hypotenuse length

C

Step-by-step explanation:

we know that

In a right triangle

The cosine of an angle x is equal to

cos(x)=\frac{adjacent\ side\ angle\ x}{hypotenuse}

The sine of an angle x is equal to

sine(x)=\frac{opposite\ side\ angle\ x}{hypotenuse}

The tangent  of an angle x is equal to

tan(x)=\frac{opposite\ side\ angle\ x}{adjacent\ side\ angle\ x}

therefore

the answer is the option C

1. Equation are,

d(t)= 6 t+2 is the equation for team A

and, d(t) = 6 t is the equation for team B

2. No , team B will not catch up to team A.

Step-by-step explanation:

Here, Team A is traveling 6 miles per hour and is 2 miles ahead of Team B.

x represents the number of hours

Then the total distance covered by A in t hours,

d(t)=6 t+ 2

And, Team B is also traveling 6 miles per hour.

Therefore, the total distance covered by B in t hours is,

d(t)= 6 t

Since, the speed of both teams are equal and already team A is 2 miles ahead of team B.

Therefore, for catching up to team A team B must be increase its speed.

Otherwise, It can not catch up team A.
