For a your meant to draw a graph (I don’t know what graph) and for b use the domain to figure out the minimum and maximum range values
Answer: just want points tbh
Step-by-step explanation:
Answer:
Step-by-step explanation:
a1=90-a2
a1=90-30=60
a2 is opposite 30 and opposite angles are equal so
a2=30
The sum of the angles of a triangle are equal to 180 degrees.
a2+a3+70=180
a3+30+70=180
a3=100=180
a3=80
White figure Area = 128![\pi](https://tex.z-dn.net/?f=%5Cpi)
White surface area = appro. 301
Yellow area = 320![\pi](https://tex.z-dn.net/?f=%5Cpi)
Yellow Surface area = approx. 653
Area found with = 2πrh+2πr2
Surface Area found with = 2πrh+2πr2
You need to memorize them for tests
Hope that helped!!! k
