Use the Law of Sines:
600 a
---------- = ---------- where 94 came from subtracting (11 + 75) from 180.
sin 11 sin 94
Solve this for side a.
To solve this, you do:
110 divided by 5 1/2.
If you want your answer in fraction form, you do:
110/1 ÷ 11/2 (the improper fraction form)
To multiply, flip the second fraction to change from dividing to mutiplying:
110/1 × 2/11
Multiply across
110 × 2 = 220 and 1 × 11 = 11
220/11
Simplify:
220 ÷ 11 = 20

.
Solution:
Given ABC is a right triangle.
AC is the hypotenuse and BD is the altitude.
AB and BC are legs of the triangle ABC.
AC = 16 and DC = 5
<u>Leg rule of geometric mean theorem:</u>



Do cross multiplication.



Taking square root on both sides.


square and square roots get canceled, we get

The length of BC is
.
Answer:
C.
Step-by-step explanation:
The relationship is proportion if y/x is constant.
So it is C because 12/4 = 15/5 = 18/6 = 3.
