2. The average distance from the sun to the planet Mercury is about 58,000,000 km. The diameter of a human hair is about 0.0025
kodGreya [7K]
Distance of Sun and Mercury = 58,000,000 km.In Scientific notation, it would be: 5.8 × 10⁷ Km
Diameter of a human hair = 0.0025 cmIn scientific notation, it would be: 2.5 × 10⁻³ cm
Before Comparison, we need to bring cms to Kms or vice-versa, so we can easily calculate then, here, we will go from cm to Km.2.5 × 10⁻³ × 10⁻⁵ Km = 2.5 × 10⁻⁸
Now, we can compare the values, 5.8 × 10⁷ Km > 2.5 × 10⁻⁸
[ reason. - power of a smaller number is in negative, it means, it is denominator, which would be very small as compared to other ]
Hope this helps!

The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 360 degrees.
serg [7]

Answer: False

Step-by-step explanation:

Triangle is a polygon with 3 sides. The formula for calculating the sum of angle in a polygon is given as :

(n-2)180

where n is the number of sides , so to calculate the sum of angles in a triangle we have :

(3-2) 180

= 1 x 180

= 180

Therefore : The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 180 degrees.
