P=2w+2l
We know that P=90 and l=15 so we can plug in and solve for w:
90=2w+2(15)
90=2w+30
60=2w
30=w
The width is 30.
(you could draw a diagram by labelling the two shorter sides 15 and the other sides w)
Hope this helps!!
You can count from 34-28 and the numbers you counted (the numbers in between 34-28) is your answer.
Answer:
c
Step-by-step explanation:
Answer:
Correct option: D
Step-by-step explanation:
In the figure we have a right triangle, that is, one of the angles is a 90° angle. Therefore, we can use the Pythagoras' theorem to find the relation between the sides of the triangle:
Where b and c are cathetus of the triangle (sides adjacent to the 90° angle) and a is the hypotenuse (opposite side to the 90° angle).
So in our case, we have that x is the hypotenuse, and 40 and 42 are cathetus, so we have:
So the correct option is D.
Diagram D has the relative locations correct.
If I were to show the bearing in a straightforward manner, I'd mark the angle NPQ as 50° and forget about angle NQP. That is, the diagram would look like that of A, but with P and Q swapped.
