Answer:
The other leg is 6 and the Hypotenuse is 6√2
Step-by-step explanation:
because it's a 45 45 90 the legs equal and the Hypotenuse is square root 2 times leg
(1-52/2+5)=(1-26+5)=(-25+5)=-20
continuing:
-20*2*6*6= -40*6*6=-240*6=-1440
result: -1440
9514 1404 393
Answer:
288 km²
Step-by-step explanation:
The surface area is the sum of the area of the square base and the area of the four triangular faces.
SA = (10 km)² + 4(1/2)(10 km)(9.4 km) = 288 km²
____
The area formulas for a square and a triangle are ...
A = s² . . . . area of a square of edge length s
A = 1/2bh . . . . area of a triangle with base b and height h
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.
