Answer:
It will be 57-2.5h=32
This is because you're starting with 57 degrees. 2.5 is constant so that is why you need a variable for it.
Well, assuming 5mm is the diameter, then 2.5 mm is the radius.
I hope this helps you
3x^2-11x-20
3x +4
x -5
(3x+4)(x-5)
The answer is d! The angle forms around the letter f therefore we need to make sure that the letter either remains in the middle or by itself. The only answer choice that does not match these options as E is in the middle is D. Hope this helped :)
Answer:
x=20
3x= 3(20)=60
4x= 4(20)=80
Step-by-step explanation:
The angles CD is 90 degrees because the small square indicates
it. Angles AD are a straight angle, therefore all the other angles within A to D, must equal 180 degree. (straight line/angle=180 degrees).
so AB + 70+ 90= 180 degrees
AB= 180 -70-90
AB=20
x=20
3x= 3(20)=60
4x= 4(20)=80
