Answer:
m<2 = 56°
Step-by-step explanation:
m<1 and m<2 are supplementary angles and sum = 180
so
m<1 + m< 2 = 180
If m< 1 = 10x + 4 and m <2 = 5x-4, find m< 2
10x + 4 + 5x - 4 = 180
15x = 180
   x = 12
m<2 = 5(12) -4 = 56
Answer
m<2 = 56°

Answer:  Arun is now 20, Shree is 10 years old
Step-by-step explanation:  
In the system of equations Arun's age is a. Shree is s
a = 2s .(current age equation)  Subtract 5 from each for five years ago,
a-5 = 3(s-5) . Substitute 2s for a in the second equation 
2s -5 = 3(s-5)  distribute and reorganize
2s-5 = 3s -15 .   15 - 5 = 3s - 2s
10 = s .  Substitute into the first equation to find a
a = 2(10)
a = 20 
5 years ago  Shree was 5 and Arun was 15
