Answer:
39 miles per hour
Step-by-step explanation:
195 miles divided by 5 hours(195/5) would be 39mph.
The required value of the acute angle x in a right angle triangle is 20. Option A is correct.
Given that
In a right triangle, the acute angles have a relationship,
sin (2x+4) = cos(46)
To determine the value of x
<h3>What are trigonometric equations?</h3>
These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operation.
sin (2x+4) = cos(46) - - - - - -(1)
Since,
cos(46) = cos (90 - 44)
cos(46) = sin (44)
put it in equation 1
sin (2x+4) = sin (44)
2x + 4 = 44
2x = 44 - 4
2x = 40
x = 20
Thus, the required value of the acute angle x in a right angle triangle is 20. Option A is correct.

Answer:
25
Step-by-step explanation:
625 = 11(d) + x(a)
625 = (11x25) + 14a
625 = 275 + 14a
350 = 14a
a = 350/14
a = 25
Therefore, 25 tickets were purchased ahead of time.
