Kazeer [188]3 years ago

Answer:

<h2>x = 15.6</h2>

Step-by-step explanation:

In order to find x we use the cosine rule, since we have all two sides and an angle

So we have

x² = ZX ² + XY² - 2(ZX)(XY) cos X

From the question

ZX = 13

XY = 8

X = 93°

Substituting the values into the expression we have

x² = 13² + 8² - 2(13)(8)cos 93

x² = 169 + 64 - 208 cos 93

x² = 233 - 208 cos 93

x² = 243.885

Find square root of both sides

x = 15.616817

We have the final answer as

<h3>x = 15.6 to the nearest tenth</h3>

Hope this helps you

K = 7 since it is literally the same in terms of slope. Its just the constant that changes and therefore it is equal to the units mentioned.

riadik2000 [5.3K]

Answer:

\frac{(\sin 18^\circ)}{75} = \frac{(\sin 35^\circ)}{x}

Step-by-step explanation:

Incomplete question:

<em></em>\angle CBD = 53^\circ<em></em>

<em></em>\angle CAB = 35^\circ<em></em>

<em></em>AB = 75<em></em>

<em></em>

<em>See attachment for complete question</em>

Required

Determine the equation to find x

First, is to complete the angles of the triangle (ABC and ACB)

\angle ABC + \angle CBD = 180 --- angle on a straight line

\angle ABC + 53= 180

Collect like terms

\angle ABC =- 53+ 180

\angle ABC =127^\circ

\angle ABC + \angle ACB + \angle CAB = 180 --- angles in a triangle

\angle ACB + 127 + 35 = 180

Collect like terms

\angle ACB =- 127 - 35 + 180

\angle ACB =18

Apply sine rule

\frac{\sin A}{a} = \frac{\sin B}{b}

In this case:

\frac{\sin ACB}{AB} = \frac{\sin CAB}{x}

This gives:

\frac{(\sin 18^\circ)}{75} = \frac{(\sin 35^\circ)}{x}

Write the equation of this line from the table provided.
Ugo [173]

Answer:

y=2x-1

Step-by-step explanation:

If you are supposed to write the equation in slope-intercept format, (y=mx+b), then y=2x-1 would be the answer. 2 is the slope(m), and -1 is the y-intercept(b). I hope thus helped :).
