Answer:
C≈62.83
Step-by-step explanation:
Use the formula C=πd
Plug in 20 for d and simplify
You then get 62.8318530718 in a calculator
So, you round it to 62.83

Answer:
obtuse triangle
Step-by-step explanation:
only one angle in a triangle has to be over 90 degrees for it to be and obtuse triangle
hoped this helped
Answer:
yes
Step-by-step explanation:
youre trying to find when -1/4x + 3/2 = -x+ 3
so if you set it up like that and then solve for x you get 2
then, you know that 2 is your x value so just plug in x into one of the equations to get the y value
(i used -x+3 bc its easier)
-2+3=y
y= 1
so your solution is (2,1)
also heres the graph
Answer:
x=13
Step-by-step explanation:
we can guess that the three angles are a linear pair and equal 180
in this case we can start writing a equation
x+105+62=180
now we can subtract both whole numbers from 180 but that takes longer, so we will combine the whole numbers on the left side.
x+167=180
now we can go ahead and subtract 167 from both sides. by doing so, it isolates the x and gives you your answer
180-167=13
so... x=13
