The markings indicate the figures are congruent. The orientation of both figures is clockwise, so no reflection is involved. The direction of QR appears to be 90° counterclockwise from the direction of EF, It appears as though the center of rotation is somewhere in the triangle EGS.
The transformation appears to be a 90° CCW rotation.
X = 1/cos(30)
X = 1.154700538
X = 1.2 (nearest tenth)
so we know the tiffany added 50 and 22 in her account and we know her balance is 306 so to find out how much she earned we have to calculate how much she earned in this case
balance
306-22
306
- 22
_______
284
- 50
2 3 4
so 234 is our answer and we can check our and by seeing if it calculates to
306
234
+ 50
2 8 4
+2 2
306
The answer is 17/5. You have to take the whole number, multiply that by the denominator. Then add that number to the numerator to get the new numerator and the denominator stays the same as before (5)
