Question

Pls help me with the two parts that I have marked with blue pen

Answer 1

Step-by-step explanation:

C) Ans =

5 x = z (Opposite angles)

5x = 180°

x = 180° ÷ 5

X = 36 °

(It means z is also equal to x )

Z = 36°

X + 40° + 5x + x + y + z = 360° ( sum of all angles )

36° +40° + 5 × 36° + 36°+ y +36° = 360°

328° + Y = 360°

Y = 360° - 328°

Y = 32°

Ans = X = 36° , Y = 32° , Z = 36°

D) Ans =

= ) X = 15° ( Opposite Angle )

=) 3x = Z + 10 ( Opposite Angle)

3x = 3 × 15 = 45

3x = z + 10

45 = z + 10

z = 45 - 10

Z = 35°

Ans = X = 15° , Z = 35°

I hope It will help
