Step-by-step explanation:
Take the new amount
Subtract the original amount
( original - new)
Then divide by the original amount
( original - new)/ original
Multiply by 100% to get the percent loss
( original - new)/ original * 100 %
Answer: 
Step-by-step explanation:
The given expression: 
Here, 

That is

The Given Triangle PMO is a Right Angled Triangle with m∠M = 90°
Given m∠P = 40°
We know that : Sum of Angles in a Triangle = 180°
⇒ m∠P + m∠M + m∠O = 180°
⇒ 40° + 90° + m∠O = 180°
⇒ 130° + m∠O = 180°
⇒ m∠O = 180° - 130°
⇒ m∠O = 50°
We can notice that m∠O and m∠1 form a Linear Pair (180°)
⇒ m∠O + m∠1 = 180°
⇒ 50° + m∠1 = 180°
⇒ m∠1 = 180° - 50°
⇒ m∠1 = 130°
Last Option is the Answer
