The answer is 98 degrees relative to the axis(probably u or v axis ) due to the fact that complementary angles are 90 degrees or it could be 8 degrees if you take the u or v axis as a constraint axis
Answer:
This a 45 degree angle
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
Given that AB and CD are parallel lines, then
∠c and ∠e are same side interior angles and are supplementary
Since the sine and cosine functions are cofunctions, they are complementary. The format for this is that sinx=cos(90-x). This works for secant and cosecant and tangent and cotangent. So, sin25°=cos65°.
Answer:
b) 
e) 
Step-by-step explanation:
Given
The attached triangle
Required
The true statement about B
The given options show that we determine the correct trigonometry ratio of B.
So, we have:
This gives:
Where:
3 cancels out
Rationalize
Also:
This gives:
Where:
3 cancels out
Rationalize
Lastly:
This gives:
<em>Hence, (b) and (e) are true</em>
