B=5
You need to get b by itself on the left side. 4b is multiplying 4 to b. You need to the opposite when you want the variable by itself. You would divide 4 to each side. 4 cancels out on the b so it turns into b. Then 4 divided by 20 is 5. B=5
Answer:
yes
Step-by-step explanation:
I believe the answer to that is <
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>°
4w-12=6w-36+14
4w-12=6w-22
10=2w
5=w
(I think)
