How do you solve for b?
AD is drawn perpendicular to BC ,m(BAD)=alpha,and m(CAD)=beta Prove that:AD=a*cos(alpha)*cos(beta)/sin(alpha+beta)
please describe whole process
I am working on a sheet, and I do not understand how to use a verbal expression to express an equation. I have never heard of it before, and I am expected to solve problems using this.
Can you show me how to proof that this triangle in both situations as fast as you can thanx in advance
AB=4.2cm BC=5.6cm D is the midpoint of AC, BD=3.5cm Calculate the length of AC
m(<B)=60• ,it's perimeter=13cm and the length of the minor diagonal=3.5cm find the length of AB and BC
AB=40cm AC=60cm cosB=-11/24 calculate the length of BC and the measure of angle A
in triangle ABC prove that: tanA/tanB = a2+c2-b2 /b2+c2-a2
