Answer:
Angle of the intercepted arc is equal to the angle at the centre (central angle) but B is not the centre hence XBY is not 144°.
Angle at the circumference (inscribed angle) is half of the central angle, but XBY is not the central angle, so it's not 2×72.
Hence not 144°
The width would be 22. Add 18+18 to get both of the sides for height which is 36z Then, subtract that from 58 which equals 22.
Answer:
x² - 64
Step-by-step explanation:
Given
(x + 8)(x - 8)
Each term in the second factor is multiplied by each term in the first factor, that is
x(x - 8) + 8(x - 8) ← distribute both parenthesis
= x² - 8x + 8x - 64 ← collect like terms
= x² - 64
The degree of this expression is 6. well you have to add all the power of the variables if it's in product form.
(a+b)/6
Add the two together and divide by six; thus one-sixth the SUM of A & B
