BAC = 70o, ACB = 80o.
Find the length of the altitude AD.

a.
3 cm
b.
4 cm
c.
213 cm
d.
33 cm


Solution:

ABC + BAC + ACB = 180o
[Since sum of the angles in a triangle is 180o.]

ABC = 180o – (70o + 80o) = 30o
[Substitute and simplify.]

In ΔADB, AD = (AB) sin (ABC)

6 sin30o = 6 × 1 / 2 = 3 cm
[Substitute and simplify.]
