Answer is 4.
Right angle= 90
50+ 10(4)= 90
Answer:
yes the answer is proportional!! :)
Step-by-step explanation:
We know that
<span>An<span> exterior angle</span></span><span> is one that has its vertex at an outer point of the circumference
</span><span>The measure of the external angle is the semidifference of the arcs that it covers
</span>
so
∠NOP=(70-30)/2-----> 20°
the answer is
<span>∠NOP=20</span>°
Answer:The line that is congruent to angle 4 is angle 1
hope this helped :)
