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) =
Answer:
Step-by-step explanation:
The whole triangle and small triangle are similar (AA). Therefore the sides are in proportion:
<em>cross multiply</em>
<em>use distributive property</em>
<em>subtract 220 from both sides</em>
<em>divide both sides by 55</em>
Answer:
500
Step-by-step explanation:
Given: P = 150 - T where P is passenger cars and T is trucks
10P = 7T ⇔ P =
Plug in equation 2 into equation 1:
= 150 - T
Solving for T, we get 500
