How I get x for number 7

Mathematics
1 answer:
lakkis [162]3 years ago
6 0

Answer:

x = 50

Step-by-step explanation:

Angles of a triangle add up to 180°.  So the third angle of the triangle on the right is:

180° − 43° − 57° = 80°

Vertical angles are congruent, so the angle on the other side is also 80°.  Therefore:

x° + x° + 80° = 180°

2x° = 100°

x = 50

A person's heartbeat is 88 beats per minute. If his/her heart beats 3.1e9 times in a lifetime, how long (in whole years) does th
Anit [1.1K]
We can solve this problem by the rule of three.

88 beats-------------------1 minute
3.1*10⁹ beats------------    x

x=(3.1*10⁹ beats * 1 minute) / 88 beats=35227272.73 minutes.

Now, we express this amount of time in years.

1 year=365 days
365 days=365 day*(24 hour/1day)*(24 hour /1day)*(60 minutes /1hour)=
=525600 minutes.

525600 minutes----------------------1year
35227272.73 minutes----------------x
 
x=(35227272.73 minutes * 1year) / 525600 minutes=67.0229 years
≈ 67 years.

Answer:this person can live 67 years.
