We know that

<span>The measure of the interior angle is the half-summit of the arcs that comprise it and its opposite.

see the attached figure with letters to better understand the problem

measure of the arc ADCB is equal to 180 degrees
arc DC=180-(arc BC+arc AD)----> arc DC=180-(60+70)---> 50</span>°
<span>arc DC=50</span>°
<span>so
</span>∡x=(1/2)*[arc AB+arc DC]---> (1/2)*[180+50]----> ∡ x=115°
<span>
the answer is
x=115</span>°

A product is now £50, the product was reduced by 20%, what was the original price
olga nikolaevna [1]

the original price is "x", or 100%.

but we know that if we reduce "x" by 20%, namely 100% - 20% = 80%, the 80% of "x" is really £50, what is "x" or the 100% anyway?

\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 50&80 \end{array}\implies \cfrac{x}{50}=\cfrac{100}{80}\implies \cfrac{x}{50}=\cfrac{5}{4}\implies 4x=250 \\\\\\ x=\cfrac{250}{4}\implies x=62.5
