2x + 100 = 5x + 55
3x = 45
x = 15
2(15) + 100 = 130
180-130 = 50
so angle 2 is 50 degrees
Temperature goes down up to 10° Celsius during the night.
Given that;
Temperature drop from 5º Celsius to -5º Celsius
Find:
Change in temperature in Celsius
Computation:
Change in temperature = Initial temperature in Celsius + Final temperature in Celsius
Change in temperature = 5 - (-5)
Change in temperature = 5 + 5
Change in temperature = 10° Celsius

Answer:
The probability that the card will be a heart or a face card is P=0.4231.
Step-by-step explanation:
We have a standard deck of 52 cards.
In this deck, we have 13 cards that are a heart.
We also have a total of 12 face cards (4 per each suit). So there are 3 face cards that are also a heart.
To calculate the probability that a card be a heart or a face card, we sum the probability of a card being a heart and the probability of it being a face card, and substract the probability of being a heart AND a face card.
We can express that as:
