30 100
x 70
x= (30*70)/100=21
√144 √ ( 12×12 )=√ (12)² = 12 ⇒ √144 = (12)²
you can use the value of sin\
sin(theta) = 12/16
Now solve for theta, and do inverse sine
so theta would be 48.59037789
, or around 50 degrees
Answer:
78.5 feet
Step-by-step explanation:
The formula for area of a triangle is A = π*r².
Put in the value of r or the radius and solve.
A = π x 5²
A = 78.53981634
A ≅ 78.5
Divide 4.55 by 0.13 (the cost of each bolt) to find out how many bolts Heidi can buy!
$4.55 ÷ $0.13 = 35
Heidi can buy 35 bolts with $4.55 !1
