C ) 131 is the answer
in the upside-vertex (not inverted) triangle, angle to your left hand side would be equal to x (as interior alternate angles) = 68
and the angle to the right would be 180-y= 180-117 = 163 (as linear angles)
so the angle at the vertex = 180 - (68 + 163) =49 (as angles in a triangle sum upto 180)
so the angle mz = 180 - 49 = 131 degrees (as linear pair of angles or angle in a straight line)
Answer:
Simple!
All you have to do is divide 3.5 by 124.25
124.25 / 3.5 = 35.5
Your answer is C.
Hope this helps!
I believe the first graph in the shape of the \_/ is the correct graph because when he gets off the freeway his speed slows then he stops and is no longer moving for a period of time. Then he gets back on and his speed is going up.
When we need the cosine of the sum of two angles, we use the addition formula for cosine.
When we need the sine of the difference of two angles, we use the difference formula for sine.
Let's try one. Say we needed to know

We're only expected to know the trig functions of 30/60/90 and 45/45/90 triangles. Fortunately,

so
