Which question ? Are you looking for?
Answer:
Step-by-step explanation:
to find slope: the formula is:
(y2-y1) / (x2-x1)
in this case it is:
(-9-(-2)) / (-10-(-2))
-7/-8
and thats the slope (that was for question one, and also an example, now do the same for questions 2, 3 and 4!!
hope thsi helps!!
Answer:
I think so Last 3 figured are the correct answer
The angles and length of the triangle area as follows:
- ∠CBD = 61°
- ∠A = 35°
- AD = 32.77 units
- BD = 22.94 units
- BC = 11.12 units
- CD = 9.73 units
<h3>How to find the sides and angle of a triangle?</h3>
The sum of angles in a triangle is 180 degree.
Therefore,
∠DBC = 180 - 29 - 90 = 61°
Hence,
∠A = 180 - 29 - 61 - 55 = 35°
∠CBD = 61°
Using trigonometric ratios,
sin 55 = opposite / hypotenuse
sin 55 = AD / 40
AD = 40 sin 55
AD = 32.7660817716
AD = 32.77 units
cos 55 = adjacent / hypotenuse
cos 55 = BD / 40
BD = 40 cos 55
BD = 22.943057454
BD = 22.94 units
sin 29 = 22.94 / BC
BC = 22.94 sin 29
BC = 11.1215326885
BC = 11.12 units
cos 29 = CD / 11.12
CD = 11.12 cos 29
CD = 9.72577114339
CD = 9.73 units
