Answer:
<h2><u><em>
60° is your answer</em></u></h2>
<u><em></em></u>
Step-by-step explanation:
the sum of the interior angles of a triangle is 180°
180 - 70 = 110
110 = 12x + 2 + 15x
108 = 27x
108 : 27 = 4°
4 * 15 = 60° is your answer
check
15 * 4 + 12 * 4 + 2 + 70 = 180
60 + 48 + 72 = 180
the answer is good

Answer:
16.5km
Step-by-step explanation:
Liola drives 17km up a hill that is at a grade of 14 degrees. What horizontal distance, to the nearest tenth of kilometer, has she covered?
We solve using Trigonometric function of Cosine
cos theta = Adjacent/Hypotenuse
Theta = 14°
Hypotenuse = Distance up the hill = 17km
Adjacent = Horizontal distance = x
Hence,
cos 14 = x/17
Cross Multiply
x = cos 14 × 17
x = 16.495027347km
Approximately = 16.5km
The horizontal distance = 16.5km
