Answer:
Number of offices in the building = 115
Step-by-step explanation:
Let x be the total number of offices.
Then 80% x= 92 or 80/100 * x =92
Hence, x = 92*100/80 = 9200/80= 115
Step-by-step explanation:
It is an isosceles triangle , it has two equal angles both 55°.
All Isosceles triangles have two equal angles <em>a</em><em>n</em><em>d</em> two equal sides.
So in this case x +18 is equal to 3x, and to find x you will equal them to each other to create a linear equation and solve.
x + 18 = 3x
x - 3x = -18
-2x = -18
× = -18 / -2
× = 9 <em>(</em><em>a</em><em>n</em><em>s</em><em>)</em><em> </em>

Step-by-step explanation:
helicopter 1 is ahead of helicopter 2 by 90 miles
the difference in their speeds is 150 mph
