I need help finding the answer

B = 65°

2 = 65°

Step-by-step explanation:

50° + 65° + B = 180°

115° + B = 180°

B = 65°

50° + 65° + 2 = 180°

115° + 2 = 180°

2 = 180° - 115°

2 = 65°

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.

problem:

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

f(5/2) = 10/3

i hope this !
