A=2916, you take 54 and square it
Answer:
cos60 - cos 72
Step-by-step explanation:
you can have an angle measure between 60 and 72 hence cos 60 - cos 72
hope this helps
Answer:
h = 9.87 cm
Step-by-step explanation:
Given that,
Base, b = 8 cm
Height = h
Angle, 
We need to find the value of h. We can use trigonometry to find h.

So, the height of the triangle is 9.87 cm.
Part A: The answer is PR = 15.23 by Pythagorean Theorem.
The pythagorean theorem is a^2 + b^2 = c^2.
Plug in 14 for a and 6 for b to find c.
Part B: The answer is QR = 7.75.
Using the same theorem, plug 16 in for c, 14 in for a, and then you can find b.
Answer:
slope = 2.
Step-by-step explanation:
find the slope using this formula y2-y1/x2-x1
40-20/1-0 = 2/1 or just 2.
