Answer:
73
Step-by-step explanation:
Original number: XY
x = 3y - 2
10y + x = (10x + y) / 2 + 1/2
substitution: 10y + 3y - 2 = 13y - 2 = (10 * (3y - 2) + y) / 2 + 1/2
* 2 both sides and simplify: 26y - 4 = 31y - 19
31y - 26y = -4 + 19
5y = 15
y = 3
x = 7
Original number: 73
8% of 1000 = 80
8% of 1080 = 86.4
8% of 1166.4 = 93.31
8% of 1259.71 = 100.77
8% of 1360.48 = 108.8
$1469.28
Rounded: $1469
Answer:
Each of the remote angles shares one side with the angle adjacent to the exterior angle. The equation means that the sum of measures of the remote interior angles is equal to the measure of the exterior angle of the triangle.
Answer:
53°
Step-by-step explanation:
i will use ∩ to represent arc since there is no arc sign
if ∩EF = 34, then ∡EFC = 34
think of EFC as an angle in the larger circle
since EFC = 34, ABC = 34 because they are opposite angles and opposite angles are always congruent.
ABD = AB + BD = 19 + 34 = 53
