Answer: x=136 degrees
Step-by-step explanation: All 3 angles inside a triangle added together will get you 180 degrees. 46+90 degrees is 136. 180-136=44 degrees. Now a line is 180 degrees too. 180-44=136 degrees for x.
Answer:
8, 82
Step-by-step explanation:
Let x = angle measure
y = complement
y = x+74
Complements add to 90
x+y = 90
Substitute y = x+74 into the equation
x+ x+74 = 90
Combine like terms
2x+74 = 90
Subtract 74 from each side
2x+74-74 = 90-74
2x = 16
Divide by 2
2x/2 = 16/2
x=8
The first angle is 8
8+74 = 82
The other angle is 82
Answer:
36 minutes
Step-by-step explanation:
Depth of the fjord = 1308 m
Rate at which the submersible dives = 35 meters/minute
Distance to the bottom of the fjord should be 48 m
Distance the submersible has to go underwater is 
Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

The time taken by the submersible to dive the required distance is 36 minutes.
