4*7=28
5y=28
divide 5 to 28
y=5.6
Answer:
Option A
Step-by-step explanation:
The complete question is shown in the attachment.
The sum of angles in a triangle is 180 degrees.
This implies that:

m<A+138=180
m<A=180-138=42
Now we use the sine rule to find AC=b

This implies that:


Answer: C) 150°
Step-by-step explanation: all the angles are the same
You don't have the answer choices but if there were no decomposers within an ecosystem, some plants could die due to a shortage of nutrients
.
c = 2(3.14)(radius)
c = 2(3.14)(3)
<em>multiply all those numbers together to get your circumference.</em>
c = 18.84.
