The angles of a triangle should add up to 180 degrees. in the left triangle, you should find the 3rd angle
75 + 50 + y = 180
125 + y = 180
y = 55
vertical angles are congruent, so the left angle on the right triangle will also be 55 degrees.
then you do the same thing to find x.
85 + 55 + x = 180
140 + x = 180
x = 40
Answer
A = 30.25pi. PLS GIVE BRAINLIEST
Step-by-step explanation:
so if circumference is 11, and formula for circumference is 2pi*r, we can work backwards to find the radius.
Radius: 11pi/2 = 5.5pi = 5.5 is radius
Area = pi * r^2
so Area = pi*5.5^2
so A = 30.25pi left in terms of pi
Answer:
I can help you for free if you want!
Step-by-step explanation:
I'm in 11th grade, so I know most 7th-grade math things.
First move terms
2/5≥x-4/5
Next calculate
-x≥-6/5
Then change the signs
= X≤6/5
25 because 25x5=125. So there would be 25 books on each shelf. Hope this helps! :)
