The three angles of a quadrilateral are 55,73,105 what is the fourth angle

127°

Step-by-step explanation:

In a quadrilateral, sum of four angles is 360°.

Consider the fourth angle x.

so,

55° + 73° + 105° + x = 360°

x = 360° - 233°

x = 127°

i dont know

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
