please answer this

Answers
1) 8x + 6 = x + 20
7x = 14
x = 2
CORRECT OPTION -----> b)
2) see the figure in attachment
x=y
x+y=180°
Put x instead of y as they are both equal
x+x = 180°
2x = 180°
x = 180°÷2
x = 90°
x = 90° = y
CORRECT OPTION------>c
3) see the figure in attachment
It is rule that corresponding angles of parallel lines are equal
In the figure - a = a
x = x
y = y
z = z
CORRECT OPTION -------> a)
4) see the figure in the attachment
CORRECT OPTION ------> c)
5) Sum of complementary angles is 90°
Let one angle be 7x &
other angle be 8x
7x + 8x = 90°
15x = 90°
x = 90°÷15
x = 6°
One angle = 7 × 6 = 42°
Other angle = 8 × 6 = 48°
CORRECT OPTION------> b)
6) CORRECT OPTION --------> d)
7) Let the supplement be x
179 + x = 180°
x = 180° - 179
x = 1°
CORRECT OPTION --------> a)
8) 360° - 60° = 300°
CORRECT OPTION -------> c)
9) CORRECT OPTION ----------> d)
10) 90° - 30° = 60°
CORRECT OPTION ---------> c)
