I need help please. I don't quite understand it! "How are we ever going to build this bridge?" asks Omar looking out across the raging river."Let's start by finding the distance to the big rock on the other side."

Melissa replies. Moving 100 meters along the river, Melissa looks back and measures the angle between Omkar and the big rock: 33°. Melissa then instructs Omar to measure the angle between Melissa and the big rock.

From his vantage point, Omar sees an angle of 98° between Melissa and the big rock.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

the answer is d
