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>°
The scale is 1:4, as the poster's dimensions are 4 times larger than the scale drawing, which is represented by the second number in the ratio. To see this, you need to see that 15 goes into 60 four times and 20 goes into 80 four times. I hope this helped you!
Answer: 10 3/8
Step-by-step explanation:
= 50 - 19 3/4 - 19 7/8
= 10 3/8
In an arithmetic sequence, the nth term is the first term + (n-1)* difference
the fifth term=the second term +(5-2)*difference
22=10+3d
d=4
the first term=the second term-the difference=10-4=6
the nth term =6+4(n-1) or or 10+4(n-2),
I think the answer is 2 and -15. Because 2 times - 15 is -30 and 2 and -15 can be added to -1.
