Answer:

[tex] \rm x=\frac{45}{2} [/tex]

[tex] \rm \angle B=67.5 \degree [/tex]

Step-by-step explanation:

[tex] \rm x + 3x + 90 = 180 \degree [/tex]

[tex] \rm 4x + 90 = 180 \degree [/tex]

[tex] \rm 4x = 180 -90 [/tex]

[tex] \rm 4x=90 [/tex]

[tex] \rm x=\frac{90}{4} [/tex]

[tex] \rm x=\frac{45}{2} [/tex]
