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:
<3=134.75
Step-by-step explanation:
8x+26=<4
Since angles 3 and 4 are supplementary, write an equation.
(8x+26)+<3=180
Subtract 26 from both sides
8x+<3=154
divide 8 to isolate the variable
x=19.25
`19.25+<3=154
<3=134.75 degrees
Sorry if this is wrong.
