Answer:
37.68 or 37.7
Step-by-step explanation:
Circumference of a circle: 2πr
2 x 3.14 = 6.28
6.28 x 6 = 37.68 or 3.7
DB should equal CB plus DC.
First write an expression to represent DC.
(x+168)-(3x+134)
x+168-3x-134
-2x+34
Then write an equal for DC plus CB equals DB
-2x+34+71= 153+2x
-2x+105= 153+2x
-4x+105=153
-4x=48
x= -12
Now plug in the value of x to find DB
153+2(-12)
153-24
129
Final answer: 129
2100 divided by 7 will be 300
Answer:
Step-by-step explanation:
A = 150°
B = 12°
C = 180 - (150 + 12) = 18°
b = 10 cm
Apply the sine rule:
Plug in the values
Multiply both sides by sin(18)
c = 14.9 cm (nearest tenth)
It’s the last one. If you take -5 to the other side, it becomes +5 so 0+5 is 5.
