Express sin A,cos A and tan A as ratios

OverLord2011 [107]

Answer:

Part A) $sin(A)=\frac{2\sqrt{42}}{23}$

Part B) $cos(A)=\frac{19}{23}$

Part C) $tan(A)=\frac{2\sqrt{42}}{19}$

Step-by-step explanation:

Part A) we know that

In the right triangle ABC of the figure the sine of angle A is equal to divide the opposite side angle A by the hypotenuse

$sin(A)=\frac{BC}{AB}$

substitute the values

$sin(A)=\frac{2\sqrt{42}}{23}$

Part B) we know that

In the right triangle ABC of the figure the cosine of angle A is equal to divide the adjacent side angle A by the hypotenuse

$cos(A)=\frac{AC}{AB}$

substitute the values

$cos(A)=\frac{19}{23}$

Part C) we know that

In the right triangle ABC of the figure the tangent of angle A is equal to divide the opposite side angle A by the adjacent side angle A

$tan(A)=\frac{BC}{AC}$

substitute the values

$tan(A)=\frac{2\sqrt{42}}{19}$

Find the distance between the points (2,4) and (9,10).

evablogger [386]

Answer: d = 9.219544 this is kinda exact haha

Step-by-step explanation:

For:

(X1, Y1) = (2, 4)

(X2, Y2) = (9, 10)

Distance Equation Solution:

=(9−2)2+(10−4)2‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾‾√

=(7)2+(6)2‾‾‾‾‾‾‾‾‾‾√

=49+36‾‾‾‾‾‾‾√

=8‾√5

=9.219544
