Answer:
30°
Step-by-step explanation:
BF is a straight line, so therefore it is equal to 180°
Because of this we know that COF is 150°, so therefor, to find BOC, we must subtract:
180° - 150° = 30°
Answer:
The area is 12x^2
Step-by-step explanation:
You would input 10 as m into the equation
t= 0.05(10) +60
t=0.5+60
t=60.5
12 purple pens = 4 parts
1 part = 12/4 = 3
4 parts purple + 1 part blue = 5 parts
3 x 5 = 15
Answer:
r = 11.623cm (aprox)
n = 6.153cm (aprox)
Step-by-step explanation:
Proportions:
9.8 ⇔ 4.3
n ⇔ 2.7
r ⇔ 5.1
n = 9.8*2.7/4.3 = 6.153 (aprox)
r = 9.8*5.1/4.3
r = 11.623 (aprox)
