Answer:
x = 12.6
Step-by-step explanation:
Sum of measure of all the arcs of a circle = 360°
m(arc CD) + m(arc CED) = 360°
Since, m(arc CED) = (20x)°
And m(arc CD) = (8x + 6)°
By substituting these measures in teh expression,
(20x)° + (8x + 6)° = 360°
(20x + 8x) + 6 = 360
28x = 360 - 6
28x = 354
x =
x = 12.64
x = 12.6
Answer:
The simplified form is:
Step-by-step explanation:
To simplify the expression given we, need to open the brackets, and if there is power term. Then we need to group all the like terms and then arrange in the descending order of powers of the given expression.
Now the expression that is given to us is:
Here we will simplify it by grouping the like terms, as follows:
So this is the required simplified form.
