Answer:
180=2^2×3^2×5
Step-by-step explanation:
We have to obtain the factors of 180 which are prime numbers
A prime number being a number with only 2 factors.That is 1 and the number itself.
For example 5 only has 2 factors 1 and 5⇒5=1×5
Here are the first few prime numbers
2,3,5,7,11,13,.....
A number which is not prime is a composite number. Composite numbers have more than 2 factors. All composite numbers can be expressed as a product of prime factors.

Answer:
60° : 75° : 120° : 105°
Step-by-step explanation:
I like to work these by considering the relationship between a "ratio unit" and the angle it represents. Here, the sum of ratio units is 4+5+8+7 = 24. The sum of angles in a quadrilateral is 360°, so each ratio unit must stand for ...
360°/24 = 15°
Multiplying the ratio units by this value, we find the angles to be ...
(4 : 5 : 8 : 7) × 15° = 60° : 75° : 120° : 105°
