Answer:
100°
Step-by-step explanation:
the total of all angles around O on one side of AD is 180° (as that would represent a half-circle).
and the sum of the arc angles AB + BC + CD covers the whole 180°.
so, we have
180 = 55 + BC + 25
180 = 80 + BC
BC = 100°
Answer:
A
Step-by-step explanation:
Using Pythagoras theorem, we have
x^2+11^2=15^2, x^2=104, x=2*sqrt(26)
You use a closed dot with the greater than or less than with the line under the symbol or the greater than or equal to or the less than or equal to symbols. The line indicates a closed dot.
H(x) = x - 5
However, it had a domain of all real numbers such that x does not equal 3, since that would cause you to divide by 0.
Answer:
5
Step-by-step explanation:
3 - 2 = 1
3 + 2 =5
5 x 1 =5
