Z should be 63
the third angle is 180 - 168 ( adjacent angles on St line)
so the angle should be 12,
and the sum of triangle is 180,
so it should be 2z = 180 - 42 - 12
z should be 63

180 - 168 = 12

180 - 42 - 12 = 126
2z = 126

<h3>Further explanation</h3>

The percent is a number that shows a comparison of the number 100 or can be called per hundred (symbol%)

Formula used:

$\large{\boxed{\bold{Percentage\:=\:\frac{Total\:Section}{Total\:Amount}\:\times\:100\percent}}}$

Fractions either proper or mixed (consisting of numerators and denominators) or decimal forms

The percentage can be expressed as a decimal by moving the decimal point two places to the left

One way to convert proper fractions to percent forms is by multiplying the fraction by 100% or By changing the denominator to 100 because percent is the percent. Multiply the numerator and denominator with the same number

35% from Several trays of danishes are filled with cream

There are four (4) trays

18 danishes on each tray
