Answer:
Part A) Use the identity
Part B)
Step-by-step explanation:
we know that
----> by trigonometric identity
we have
substitute in the expression above
solve for tan(A)
square root both sides
Remember that Angle A terminates in quadrant IV
so
The value of tan(A) is negative
Find the value of cot(A)
we know that
----> is the reciprocal
therefore
simplify
Answer:
First answer is A.
Second answer is: tan.
Third is answer C. sqrt7/3
Fourth answer is A. -3sqrt7/7
Step-by-step explanation:
Answer:
The length of segment of OL is 22.4 cm
Option 3 is correct
Step-by-step explanation:
In ΔMNL, NM||PO
If two sides are parallel then their corresponding sides are in ratio.
Basic Proportionality Theorem: If a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in same ratio.
Therefore,
OL = x+4
OL = 18.4 + 4 = 22.4 cm
Hence, The length of segment of OL is 22.4 cm
