Answer:
x = 69
Step-by-step explanation:
The sum of the angles round a point is 360°
Subtract the sum of the 2 given angles from 360 for x
x = 360 - (168 + 123) = 360 - 291 = 69
Answer:
29
Step-by-step explanation:
(1.2 x 10-4) + (2.4 x 10-3)
Simplify
1.2 x 10- 4 = 8
2.4 x 10- 3 = 21
Add both sums to get 29!
SCIENTIFIC NOTATION
2.9 x 10 to the 1st power
Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better
