Answer:
angle b = 60°, angle c = 50°
Step-by-step explanation:
angle b: 120° - 80° = 60°
this is because a straight line is 180*, therefore given the angle 120° we can work out the other by subtracting it from 180°
angle c: 60° + 70° = 130°, 180° - 130° = 50°
this is because angles in a triangle add up to 180°, therefore given two angles we can subtract them from 180° to get the third
hope this helps! :)
2^3 * 5^2
We need to break 200 down into prime numbers
200 = 20*10 These are not prime
= 4*5 * 2*5 The 4 is not prime
= 2*2*5 * 2*5 This is prime
Rearranging
= 2*2*2*5*5
= 2^3 * 5^2

8 + h^2
Let h = 3
8 + 3^2
We find the value of 3^2 first using PEMDAS
8 + 9
Then add
The result is 17
