Hello,
Answer D 5/4
since div 15={1,3,5,15}
and div 8={1,2,4,8}
posiible rational root is a*b where a∈div 15 and b∈div 8
No, the Pythgorean Theorem only applies to right triangles. To get two right triangles, you divide a rectangle diagonally. Dividing a hexagon into two pieces produces trapezoids or pentagons depending where it is divided.
I don't know if this is right or if you're teacher will allow this, but
you could put that as 7(x+8) because if you were to turn it into a solved thing, it would become 7x+56.
I don't know if this is right though.
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
