11*11=121
14*14=196
14-11=3
121+196=317
The integers are 11 and 14
Answer:
The height is 14.3 km
Step-by-step explanation:
Given
--- angle of elevation
Required
Determine the height above the ground
The question is illustrated using the attached image.
To calculate the required height, we make use of:
Where AB represents the height and BC, the distance.
So:
Make AB the subject
--- approximated
Answer:
Distance between bottom of the wall and bottom of the ladder = 7 ft
Length of the ladder = 19 ft
Let the distance between the ground and top of the ladder be x
Using Pythagoras theorem,
x^2 + 7^2 = 19^2
x^2 + 49 = 361
x^2 = 312
Therefore x = √312 = 2√78 ft
Answer:
x=27, y=18
Step-by-step explanation:
Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.
