Answer:
x = 61°
y = 61°
z = 58°
Step-by-step explanation:
In the given triangle, measures of two sides are equal. So, measures of angles opposite to them are also equal.
Therefore,

The correct answer is 30+100u. Hope this helps!!
as the exterior angle is known
sum of that angle and f angle = 180
142 + f = 180
f = 180 - 142
f = 38
That should be the equation there looking for (10x.20)h+.50
Answer:
Time taken by the submarine to reach the cave is 10 seconds.
Step-by-step explanation:
We are given that,
The elevation of the underwater cave = -120 feet.
The rate at which the submarine descends to the cave = -12 feet per second
Thus, we have,
The time taken by the submarine to reach the cave =
= 10 seconds.
Hence, the time taken by the submarine to reach the cave is 10 seconds.
