Answer:
70 m
Step-by-step explanation:
AB makes a 30-60-90 triangle with the wall.
AC makes a 45-45-90 triangle with the wall.
In a 30-60-90 triangle, the short leg (opposite of the 30° angle) is half the hypotenuse.
In a 45-45-90 triangle, the legs are the same length.
So the distance between the left wall and the laser is 60/2 = 30 m.
The distance between the right wall and the laser is 40 m.
The total distance is therefore 70 m.
Answer:
6 4/7
Step-by-step explanation:
I personally break it down like this:
Is 2 greater than 7? No so that means the whole number would stay 5.
Same for the other number. Then add the whole numbers attached to the fraction. Which is 6. Then go to the fraction. 2/7 + 2/7 is 4/7. This cannot be simplified anyfurther.
Answer:
<h2>x > 3+y</h2>
Step-by-step explanation:
The correct answer is 64 square units.
The area of the complete shape would be 100 square inches.
10 x 10 = 100
However, we have to remove the 4 corners. Each of the corners is 9 square inches. 3 x 3 = 9
100 - 4(9) = 64
