Please help I have no clue how to do this​

Mathematics

Alinara [238K]2 years ago
5 0

Step-by-step explanation:

It's a question of trigonometry.

You need to remember that tangent (tan) stands for Perpendicular / Base.

So, tan P = QR / PR

By Pythagoras Theorem,

34² = 30² + x²

x² = 34² - 30²

x² = 1156 - 900

x² = 256

x = 16

Now, placing the values,

tan P = 30 / 16

tan P = 1.875

HOPE IT HELPS ^_^

Use the Law of Sines to find mZY.
Scrat [10]

Answer:

Step-by-step explanation:

recall law of Sines   :) the same as before  Sin(A) /a = Sin(B) / b

[ when you see it a lot.. you'll remember it  :D ]

for this problem  Z =A=123  and a = 30

Y=B and b =14

Sin(123) / 30 = Sin(B) / 14

14 * 0.0279556 = Sin(B)

0.391379 = Sin(B)

arcSin(0.391379 ) = arcSin ( Sin (B) )

23.040 = B

Y = 23.0°

are you seeing how to do these?  so you could on a test?

The equation Y-5<br> 5(x-4) is written in point-slope form. What is the y-intercept of the equation?
nirvana33 [79]

Answer:

The y-intercept is -15.

Step-by-step explanation:

y - 5 = 5(x - 4) is our equation in point-slope form.

point slope form is = y - y1 = m( x - x1)

So, we know that the slope is 5 and one point is (4, 5)

We can use this point and the slope to find the y -intercept.

y = mx + b is slope intercept form.

Let's input the values we know to find the y-intercept.

5 = 5(4) + b

5 = 20 + b

-15 = b

The y-intercept is -15.
