The distance to the nearest gas station is 2 4/5 kilometers. what is this distance
written as a decimal
1. by definition, scientific notation has the following form:
a is a number between 1 and 10 but does not include 10.
b an integer.
2. when you multiply 3.25 by 7.8 the result is 25.35 and when you multiply by , you obtain , but to write ree thsult in scientific notation, the decimal point must be after the first digit. therefore, you must move the decimal point one place to the left. so, the exponent changes from 9 to 10:
there are three angles so it means this is a triangle and sum of all angles of a triangle is always 180°. these all angles add up to 180°.
open the brackets: 65°+3x-10+2x=180°
arrange the numbers and valuables: 65°-10°+3x+2x=180°
hence, angle 1: 65°
angle 2: 3x-10°
angle 3: 2x
