Answer:
2989
Step-by-step explanation:
Always start with the bracket
3000 + 9 = 3009
3009 - 20 = 2989
Answer:
x=14
Step-by-step explanation:
The interior angles of a regular decagon are the same and add up to 1440.
10(10x+4)=1440
414 is 92% of 450
Therfore, when you subtract 100 - 92
It equals 8
8% is the answer.
The measures of vertical angles are identical.
∠A = ∠B
x+16 = 3x-14 . . . . substitute the given measures
30 = 2x . . . . . . . . add 14-x
15 = x . . . . . . . . . .divide by 2
∠A = ∠B = 15+16 = 31
The measure of ∠A is 31°.
