Answer:
Yes, it is an arithmetic Sequence. Can you explain the question just a tad more
Step-by-step explanation:
Answer:
11
Step-by-step explanation:
your welcome bro.
The angle whose sin is 0.78 is either <em>51.26</em> degrees or <em>128.74</em> degrees.
(rounded)
There's no simple way to calculate this. You just have to look it up in a book
or punch it into your calculator.
Answer: 34 degrees
Step-by-step explanation:
bisects means split evenly, angles are equal
Step-by-step explanation:
this is not an isoceles triangle.
anyway, we need to remember 2 things :
1. the sum of all angles in a triangle is always 180°.
2. the sum of all angles around a single point on a line is 360° (as this point wound be the center of an invisible circle). and as the line cuts this circle in half, the angles on one side of the line around this point is therefore 180°.
so, the internal angle Q is then
180 = 50 + 55 + Q
Q = 180 - 50 - 55 = 180 - 105 = 75°
the exterior angle x at Q is then
180 = Q + x = 75 + x
x = 180 - 75 = 105°
