Answer:
Step-by-step explanation:
The parametric equations of a circle is
and
The radius of the unit circle is 1 unit.
This implies that any point on the unit circle is represented by:
and
where is the angle in standard position,
From the question, the given angle in standard position is .
This angle intersects the unit circle at
But
We substitute and
This implies that:
you could use this equation to help you solve it;
x + (x + 42) = 138
the first step is to combine like terms;
2x = 138 -42
2x = 96
X = 96/2
X = 48
we already solved for x now substitute it in the equation I gave you.
48 + (48 + 42) = 138
48 + 90 = 138
hope it helped...if you have any concerns just let me know:)
Answer:
If their angles are the same, if they are proportional, if it states so
Step-by-step explanation:
I don't see the image you sent, but just naming different things that proves how triangles are similar.
