Can someone help with this problem (time sensitive)

∠D = 52º

∠E = 32º

∠F = 96º

Step-by-step explanation:

the sum of interior angles of a triangle equals 180º

so: (x + 20) + (3x) + 32 = 180

     3x + x + 20 + 32 = 180                  combine like terms

     4x + 52 = 180                                subtract 52 from both sides

     4x = 128                                         divide both sides by 4

     x = 32

plug x into each angle measure to get them:

∠D = (32) + 20 = 52º

∠E = 32º (given)

∠F = 3(32) = 96º

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
