109 degrees and the missing angle are supplementary angles, so they add up to 180 degrees.
180 - 109 = 71
The measurement of ULE can now be found since we now have 2 angles with their degrees. So we add those angles together...
71 + 49 = 120
Now we subtract that from 180 (all of the angles add up to 180 in a triangle) to get the m180 - 120 = 60
The m

Answer:
77.5 = 12.5t
6.2 mins.
Step-by-step explanation:
The scuba diver was at the sea bed from where the water surface is at 77.5 m height. The ascending speed of the diver is 12.5 m/minute.
a. If the diver take t minutes to reach the water surface, then the equation that models the situation is
77.5 = 12.5t ......(1)
b. If we consider the sea bed as a reference level i.e. zero height, then the sea surface will be at 77.5 m height.
Therefore, in that case, it is reasonable to write the distance 77.5 m as a positive number.
c. Solving the equation (1), we get, t = 6.2 minutes.
So, the diver will take 6.2 mins to reach the surface. (Answer)
The ratio would be 3:1
( the 6 triangles are blue, which I’m pretty sure they are.)
Since there are 18 yellows and 6 blues, and the question calls for the ratio of the yellows to the blues, the ratio is 18:6. But you always have to simplify. The GCF is 6, so you would divide both of them by 6. The ratio is then 3:1.
