In triangleABC, C is the right angle. If tanA = 8/6, find cosB

klemol [59]

<u>Short answer</u> = C) 8/10

<u>Working :</u>

Tan A = 8/6 = Opposite / AdjacentOpposite = 8 units

Adjacent = 6 units

Hypotenuse = $\sqrt{8^{2} + 6^{2} }$

= $\sqrt{64 + 36 }$

= $\sqrt{100}$

= 10 units

Cos B = Adjacent/ Hypotenuse

∴ cos B= 8/10

Identify the slope of the equation, substitute by distribution I think, substitution for given point coordinates the y-intercept and combined like terms. And rewrite the equation in y-intersect form. I think this is write, have a great day!

Question 1 of 10

statuscvo [17]

Answer:

slope is -1

Step-by-step explanation:

Slope of the line is changes in y over changes in x. It can also be referred as rise over run.

We can express mathematically as:

$\displaystyle{m=\dfrac{y_2-y_1}{x_2-x_1}}$

where m is slope.

Let (-2,5) be $\displaystyle{(x_2,y_2)}$ and (6,-3) be $\displaystyle{(x_1,y_1)}$ . Hence, apply the slope formula:

$\displaystyle{m=\dfrac{5-(-3)}{-2-6}}\\\\\displaystyle{m=\dfrac{5+3}{-8}}\\\\\displaystyle{m=\dfrac{8}{-8}}\\\\\displaystyle{m=-1}$

Therefore, the slope is -1
