Answer: Choice C
sin(26) = x/10
===========================================================
Explanation:
With respect to the 26 degree angle, the x is the opposite side and the 9 is the length of the adjacent side.
We can say tan(26) = x/9 because tangent is the ratio of opposite over adjacent. In other words, tan(angle) = opposite/adjacent
Unfortunately, tan(26) = x/9 is not an answer choice.
Luckily though, we have other trig ratios to work with.
The sine ratio ties together the opposite side and hypotenuse
sin(angle) = opposite/hypotenuse
sin(26) = x/10

Extra info (optional section)
Solving for x leads to...
sin(26) = x/10
10*sin(26) = x
x = 10*sin(26)
x = 4.38371 approximately
Also, note how cos(26) = 0.89879 approximately, which is fairly close to 9/10 = 0.9. This indicates some rounding error is going on when your teacher is displaying either the 9, the 10, or the 26 degree angle.
Answer:
d
Step-by-step explanation:
The secant- secant angle 1 is one half the difference of the measures of the intercepted arcs, that is
∠ 1 =
(a - b)°
cost = 34.75 + 2.99m
where m is the number of movies purchased per month.
If Absolute cable lowers the service fee ($30), how will the expression change?
cost = 30.00 + 4.75 + 2.99m
The 30.00 will be lowered. Therefore, the cost will decrease.
Answer:
The cost [constant] will decrease.
Answer:
12w+15
Step-by-step explanation:
Distribute 3 to whats inside of parentheses
3*4w=12w
3*5=15
12w+15
Answer:
all
Step-by-step explanation:
first we can combine 5x and - 2x
5x + -2x = 3x
now we have 3x + 5 > 11
now we can go through all of the numbers to see which numbers make the inequality true
3 yes
3 * 3 = 9
9 + 5 = 14
so all of the numbers make it true
