Pls Answer it I will Mark BRAIN LIST.

cosA = 40/41

tanA = 9/40

Step-by-step explanation:

Step 1: Find the other leg value

a² + b² = c²

9² + b² = 41²

b² = 41² - 9²

b = √1600

b = 40

Step 2: Draw out your triangle.

When you do so, you should see the cosA (adjacent over hypotenuse) is 40/41 and tanA (opposite over adjacent) is 9/40.

Triangle CBA

Length of AC = 40 (Leg)

Length of BC = 9 (Leg)

Length of AD = 41 (Hypotenuse)

cosA = AC/AB = 40/41

tanA = CB/AC = 9/40

Cos A = 40/41

Tan A = 9/40

Step-by-step explanation:

Sin A = =

So,

Perpendicular = 9 , Hypotenuse = 41

So, Finding base by Pythagorean Theorem

=>

=>

=>

=>

Taking sqrt

=> base = 40

Now,

Cos A =

Tan A =

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
