Answer:
82°
Step-by-step explanation:
i. 8x +26 = angle 5 (corresponding angles)
ii. angle 5 = -9x + 179 ( vertically opposite angles)
so,
8x+26= -9x +179 (from i and ii)
or, 17x= 153
therefore, x= 9
now,
angle3 + 8x +26= 180° (linear pair)
angle 3 = 180°- 72-26
hence, angle 3= 82°
Answer:x=-43
Step-by-step explanation:
To expand (x-11)(4x+1) to get x
x^2+x-44x-11
x^2-43x-11
So x=-43
