At most, 20. 20 is the greatest common factor of all numbers.
Basically the total of the line or any line is 180°
if one side is 129°
then the other is 180-129
which means x = 51°
<h3>The distance between two landmarks is 123 meters</h3>
<em><u>Solution:</u></em>
We have to find the distance between two landmarks
<em><u>Use the law of cosines</u></em>
The third side of a triangle can be found when we know two sides and the angle between them
Here, angle between 90 meters and 130 meters is 65 degrees
From figure,
a = 90
b = 130
c = d
Therefore,
Thus, the distance between two landmarks is 123 meters
Answer:
17°
Step-by-step explanation:
∠AOC is a right angle, so it measures 90°
∠AOB and ∠BOC are in ∠AOC, so m∠AOB + m∠BOC = 90
m∠AOB = 73°
m∠BOC = x (shown in the diagram)
73 + x = 90
x = 17
