What is x and measure b? please help:)

x= 22.5, angle B = 67.5

Step-by-step explanation:

90+3x+x= 180

4x = 90

x=22.5

3(22.5)= 67.5

x = 22.5° B = 67.5

Step-by-step explanation:

90° + 3x° + x° = 180°

4x = 90°

x = 22.5°

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

24

step-by-step explanation:
