The value of x is 113 because the 3 angles in a triangle add up to 180° so 180 subtracted by 28° and 39° gives the value of angle x.
The value of y is 67° because x and y are supplementary angles which means they add up to 180°. So 180-113 gives y.
The value of z is 49° because if you subtract the 180° that makes up the triangle from 67 and 64, you get 49.
C/23=2/3
C = 15.3
Answer is B) 15.3
divide the number of people by how many can sit at each table
174/4 = 43.5
so they will need 44 tables
Answer:
11
Step-by-step explanation:
5(2+4)-(2+3^3)
=5(8)-(2+27)
=40-29
=11
