The drawbridge will be at an incline of 10.56 degrees. That is 5.56 degrees more than it's initial incline of 5 degrees.
If you draw a picture of this situation, you will see that you can write a sine ratio with the 11 and 60 (opposite over hypotenuse)
sin(x) = 11/60 Solve the equation for x
x = 10.56
Answer:
By comparison of the sides.
Step-by-step explanation:
If triangles are similar, that means their angles are equal and sides are proportional.
If you already have a proportion of two corresponding sides between triangles, then use that proportion and set it equal to a side you already know the measurement to. Hopefully that side is corresponding to your missing measurement, and you can then solve it.
Lexi needs to buy 18 packages. To find the answer, divide the number of vases she needs, 105, divided by 6 (the vases per package). 106/6 is 17.5. Because you can't buy a half of a package, she would have to buy 18 packages.
If h(x) = -2x - 10 you should put the -4, -2. -18, -3 or/and -16 in the place of the x in the formula.
So for example:
h(-4) = -2 * (-4) - 10 = 8 - 10 = -2
Or at least, that's what I think the answer should be.
Good luck!
