To find the length, divide the area by the width:
Length = 135 / 9 = 15 feet.
Answer:
5/13
Step-by-step explanation:
According to SOH CAH TOA
cos theta = adj/hyp = -12/13
Get the opposite using pythagoras theorem
13^2 = (-12)^2 + opp^2
169 = 144 + opp^2
opp^2 = 169-144
opp^2 = 25
opp = 5
Get sin θ
sin θ = opp/hyp
sin θ = 5/13
hence the value of sin θ is 5/13
Answer:
255.75
Step-by-step explanation:
multiply them all together
31/2*3*11/2
Answer:
Step-by-step explanation:
Given
Required
Complete the triangle (See attachment)
First, calculate side a using cosine's equation
Take square roots
The measure of B and C can then be calculated using sine's equation
So:
Cross multiply
Solve for sin B
Take arc sin of both sides
To calculate C, we make use of:
--- angles in a triangle
Collect like terms
