Answer:

CAB = 70°

YZW = 120°

Step-by-step explanation:

CBA = 90° (right angle in a semicircle)

CAB = 180° - CBA - ACB ( angle in a triangle is 180°)

CAB = 180° - 90° - 20°

= 70°

YZW + YXW = 180° (opposite angle are supplementary in a cyclic quadrilateral)

YZW = 180° - YXW

= 180° - 60°

= 120°

(Correct me if i am wrong)

Darlene has 59 pages to type. so far she gas type 23 pages. what fraction of the job is finished

coldgirl [10]

Answer:

$\frac{23}{59}$

Step-by-step explanation:

A fraction can be found be taking the current amount over the total amount:

$\frac{current}{total}=\frac{23}{59}$

Since Darlene has only typed 23 pages out of 59, her fraction is 23 over 59. Fractions must always be in simplest form, which means that both the numerator and denominator can no longer be divided by the same factor. Since the numbers 23 and 59 are both prime and have no other factors other than 1 and themselves, the fraction 23/59 is in simplest form.
