Answer:
x=28
Step-by-step explanation:
Usually triangles equal 180 so if that's the case then you just add all of the angles together and set it equal to 180. So your equation should be 50+ 2x+ 3x-10= 180 and then solve that equation and you will end up with x=28. Hope this helped!!
5.2 x 10^-3 - 2.58 x 10^-3 Since the exponents on the 10 part is the exact same you can just subtract the number parts
5.2 - 2.58 = 2.62
Add the x 10^-3 back to it and get 2.62 x 10^-3
