To solve this problem, you must know that an inscribed angle equals 1/2 of the arc that it intercepts.
Therefore, because <ABC intercepts arc ADC, we know that
the measure of angle ABC = 1/2 * (measure of Arc ADC)
OR, when the values are substituted into the equation
165 = (1/2) (5)(x-3)
When simplified, this equation equals
330 = 5x - 15
345 = 5x
x = 69
Therefore, your answer is the second option, that x = 69 degrees.
Answer:
3m - 25
Step-by-step explanation:
3m - 25 will represent how many minutes she practiced this week:
3m represents 3 times the number of minutes she practiced last week. Then, subtract 25 from this.
This will represent 25 minutes less than 3 times the number of minutes she practiced last week.
Answer: simplify g(x) = 8x^2- 4x -9
2.86
= 28 tenths + six hundreths.
(The number directly after the decimal point is an hundreth)
Since there is a 2.0 (twenty tenths), the answer is:
20+8 = 28 tenths.
