Find the measure of angle L this is the last question mark brainest ty so much xx

Step-by-step explanation:

see attached image.

add all internal angles and equal to 180

∠U + ∠L + ∠E = 180

∠U = 180 - 109

     = 71

plug in values from equation:

∠U + ∠L + ∠E = 180

71 + ∠L + 49 = 180

∠L = 180 - 49 - 71

∠L = 60

5x+2x=49

7x=49

x=7. 35 apples

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons
