5) x = 8
6) z = 49°
- Step-by-step explanation:
Hi there !
5)
we have opposite angles =>
5x = 2x + 24
5x - 2x = 24
3x = 24
x = 24 : 3
x = 8
6)
The sum of the three interior angles in a triangle is always 180° !
x = 180° - (28° + 39°)
= 180° - 67°
= 113°
x ; y = supplementary angles =>
x + y = 180° =>
y = 180° - x
= 180° - 113°
= 67°
z = 180° - (64° + 67°)
= 180° - 131°
= 49°
Good luck !
