9 * 3 - 4(16/7) = 189/7 - 64/7 = 125/7 = 17 <em>6/7 </em>
Answer:
The value of cosθ is
Step-by-step explanation:
It is given that an angle θ with the point (15, −8) on its terminating side.
Here x=adjacent side=15 units and y=opposite side =-8 units,
Using pythagoras theorem,
Cosine is defined as
Therefore the value of cosθ is .
The bottom right
it goes like \
~\
ish.
just going by the picture it’s the only one on the second row
Two sides have the same length, which is less than the length of the third side.
The two sides they are referring to are the legs of the triangle, and the third side is the hypotenuse. We know that the legs are congruent because their base angles are congruent (45 and 45). We also know that they are both less than the third side because the hypotenuse is always the longest side in a right triangle. Hope this helps!
