Answer:
The triangle are similar and the missing line is 16.5
Step-by-step explanation:
The reason is because the scale factor is 2. You can find this out by multiply 8×2=16 and 9×2=18. With this in mind you divided 11 by 2 to get 5.5 for LD. Finally, adding 11+5.5 you will get 16.5.

Answer:
45 miles in 1 hour
Step-by-step explanation:
1 hour is 60 minutes
22.5 miles / 30 minutes * 2/2 = 45 miles / 60 minutes = 45 miles in 1 hour
Answer: the angle is 35 degrees
The supplementary angle is 145 degrees
Step-by-step explanation:
Supplementary angles are angles whose sum is 180 degrees. This means that if angle x and angle y are supplementary, then the sum of angle x + angle y is 180 degrees.
The given angle measures 110° less than the measure of its supplementary angle.
Let the angle be x degrees and the supplementary angle be y degrees. This means that.
x = y - 110
Recall, sum of supplementary angles is 180 degrees. Therefore,
x + y = 180 - - - - - - - - 1
Substituting x = y - 110 into equation 1, it becomes
y - 110 + y = 180
2y -110 = 180
2y = 180 + 110 = 290
y = 290/2 = 145 degrees
x = y - 110 = 145 - 110
x = 35 degrees
Heyyyyyyyyyy! I think 1 of each because- y’a I just think that.
