Answer:
Step-by-step explanation:
5h-8=2h+19
5h-2h=19+8
3h=27
h=27/3
h=9
Since you need a little bit of trigonometry to solve this problem,
I'm pretty sure you've had a little bit of trigonometry in class before
you were assigned to solve this problem.
-- The shaded triangle comes from taking the equilateral triangle and
either folding it in half or cutting it in half.
-- The base that the new triangle is standing on is 1/2 the base of the
equilateral triangle, so it's 7 cm long.
-- The acute angle at the right end of the base is the same as it was in
the equilateral triangle . . . 60 degrees.
-- The tangent of 60 degrees is (opposite side)/(adjacent side) = x / 7 cm
tan(60) = x/7
-- Multiply each side of this little equation by 7 : 7 tan(60) = x
If you don't have the tangent of 60 degrees in your pocket, you can
find it with your calculator. Multiply it by 7, and Shazam, you know 'x' .
Answer:
30°,40°
Step-by-step explanation:
let the other angles be 3x and 4x
3x+4x+110=180
7x=180-110=70
x=70/7=10
3x=3×10=30
4x=4×10=40
I think the answer is c for the graph
Answer:
<h2>
11.4</h2>
Solution,
∆ ACB = ∆ EFD
finding the value of X,
![\frac{x}{3.8} = \frac{15}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B3.8%7D%20%20%3D%20%20%5Cfrac%7B15%7D%7B5%7D%20)
Apply cross product property
![x \times 5 = 15 \times 3.8](https://tex.z-dn.net/?f=x%20%5Ctimes%205%20%3D%2015%20%5Ctimes%203.8)
Calculate the product
![5x = 57](https://tex.z-dn.net/?f=5x%20%3D%2057)
Divide both sides by 5
![\frac{5x}{5} = \frac{57}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5x%7D%7B5%7D%20%20%3D%20%20%5Cfrac%7B57%7D%7B5%7D%20)
Calculate
![x = 11.4](https://tex.z-dn.net/?f=x%20%3D%2011.4)
Hope this helps...
Good luck on your assignment...
