Presuming the circle is the whole, 1/4 + 1/2 is 3/4, or 0.75, so it is 75% of the circle.
Step-by-step explanation:
It’s 130°, because 50+50=100 and 2x is equal to the same angel on the direct opposite side so work where you have 50. then the 4 angles should add to 360° and 360-100= 260, then you have to divide 260 by 2 because it has to be equal to both side so then 260/2=130° and to know that it’s correct add 130+130+50+50 and you get 360°!
Answer:
w^2 -18w + 81
Step-by-step explanation:
Simply, what we have to do here is to divide the coefficient of w by 2, then square it
we have this as -18/2 = -9
Squaring is -9^2 = 81
I guess you're supposed to write the expression on the right in terms of
