Answer:
c=sqrt21
Step-by-step explanation:
angle c is the angle between a and b, so use the cos law
c^2=a^2+b^2-2*a*b*cosC
c^2= 16+25-2*4*5*1/2
c^2=21
c=sqrt21
When you simplify 3/12, it's 1/4.
h/8 is equal to 1/4 so you want to multiply 2 for 1/4 which it becomes 2/8
Therefore h is 2
Answer:
60 feet but i think the question is written wrong
Step-by-step explanation:
Answer:
A = 63.59
C = 28.26
Step-by-step explanation:
r = 4.5
Area of a circle:
A = πr²
A = 3.14(4.5²)
A = 3.14(20.25)
A = 63.59
Circumference:
C = 2πr
C = 2(3.14)(4.5)
C = 28.26
Answer:
Quotient Rule
Step-by-step explanation:
Your dividing so its quotient. Product is multiplication.
