Answer:
x° = 83°
Step-by-step explanation:
All angles in a triangle (any kind of triangle: right, isosceles, equilateral etc.) add up to 180 degrees.
So, if we are given the ABC triangle, then:
angle A + angle B + angle C = 180°
In this particular case, we are given values of two angles, so using the previous relation, we can write:
x° + 44° + 53° = 180°
Now, it's easy to find x°:
x° = 180° - 44° - 53°
x° = 83°
Answer:
The answer is: x < 2

Answer:
<u>The correct answer is D. Any amount of time over an hour and a half would cost $10.</u>
Step-by-step explanation:
f (t), when t is a value between 0 and 30
The cost is US$ 0 for the first 30 minutes
f (t), when t is a value between 30 and 90
The cost is US$ 5 if the connection takes between 30 and 90 minutes
f (t), when t is a value greater than 90
The cost is US$ 10 if the connection takes more than 90 minutes
According to these costs, statements A, B and C are incorrect. The connection doesn't cost US$ 5 per hour like statement A affirms, the cost of the connection isn't US$ 5 per minute after the first 30 minutes free as statement B affirms and neither it costs US$ 10 for every 90 minutes of connection, as statement C affirms. <u>The only one that is correct is D, because any amount of time greater than 90 minutes actually costs US$ 10.</u>
