Answer:
c = 60.65 cm
Step-by-step explanation:
Given that,
The two sides of a triangle are 33 cm and 37 cm.
The angle between these two sides is 120°.
We need to find the length of the third side of the triangle. Let c is the third side. Using cosine rule,
a = 33 cm, b = 37 cm and C is 120°
So,
So, the length of the third side of the triangle is 60.65 cm.
Hello.
In 10 years, his age will be
The sum of his current age and 10 equals his age in 10 years.
2 years ago his age was
The difference of his current age and 2 equals his age 2 years ago.
7 years ago his age was
The difference of his current age and 7 equals his age 7 years ago.
Therefore, his age after 10 years will be , his age 2 years ago was
, and his age 7 years ago was
I hope it helps.
Have a nice day.
