Answer:
i. sin(C) =
ii. tan(C) =
iii. sin(B) =
Step-by-step explanation:
Given a right angled triangle ABC, with a right angle at A.
<ABC =
<BCA =
AC = 9 = 1
CB = 18 = 2
Applying Pythagoras theorem to ΔABC, we have;
AB =
=
=
Thus applying the trigonometric ratios, it would be observed that;
i. sin(C) =
ii. tan(C) =
iii. sin(B) =
To determine the perimeter of the pentagon, you must first calculate a side length of it. Let's name the coordinates A(-1,4) and B(2,3).
To figure out how far the points are from each other, you have to use the distance formula:
D_{AB}= \sqrt{(2--1)^2+{(3-4)^2}
Now, the formula for the perimeter of a pentagon is
P = 5×side length
So...
Perimeter = 5×
The answer is (2)
