The domain is 16,1,-13,18
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
Yeah so there’s the step by step process
X = 8
m ∠GDH = 126°
m ∠FDH = 160°
m ∠FDE = 137°
