Answer:
a = 115°
b = 40°
Step-by-step explanation:
Total angle of the pentagon, 540°, unknown angle (U) of the pentagon, 540°-90°-90°-90°-25° = 245°
a = 360°-U so,
a = 360°-245° = 115°
Now, total angle of ∆PQR is 180°
<P = 50° and <R =90°, since TU || SR
So <b = 180°-90°-50° = 40°

Answer:
As T U || SR and TR is the transversal
line
ZTRS + ZRTU ⇒ ZTRS = 90° 180°
ZP RS = ZTRS - 90° (*.*
vertically opposite angles)
In APQR,
ZP + ZQ+/R = 180°
50° +b+90° = 180°
b = 40°
