Answer:
Step-by-step explanation:
Tricky. Very neat.
You are missing the minor arcAC and you need it, but don't fret. It can be found.
The formula for this is x = 1/2(Major Arc(235) - Minor Arc(see below) )
The minor arc is the supplement of x.
The minor arc is also equal to the the central angle
So the minor arc is 180 - x
x = 1/2 (235 - (180 - x) ) Remove the inside brackets
x = 1/2 (55 + x ) Remove the remaining brackets
x = 1/2 *55 + 1/2x Subtract 1/2x from both sides
1/2 x = 27.5 Multiply both sides by 2
x = 55
Answer:
x=7
Step-by-step explanation:
To set up for this answer, we need to set it up as an equation: 2x+12=5x-9.
get the xs on one side and the whole numbers on the other.
that leaves you with 21=3x.
divide by 3 on both sides to get the answer of x=7
Answer:
263
Step-by-step explanation:
take the start amount 315 and subtract 78 then add 26 which would amount to 263
