The m∠a is 45 degrees. find the m∠b. a) 45 degrees b) 50 degrees c) 90 degrees d) 125 degrees

A) 45°

Step-by-step explanation:

∠B is a vertical angle to ∠A so there for their measurements are equivalent.

the answer will be the last one

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!
