Question

Given the figure, find the values of x and z.

Answer 1

Explanation:

• (12x-63°)=(7x-8)°
• 12x°-63°=7x°-8°
• 12x°-7x°=-8°+63°
• 5x°=55°
• x°=55°/5
• x°=11°

• (7x-8)°+z°=180°
• 7x°-8°+z°=180°
• 7×11°-8°+z°=180°
• 77°-8°+z°=180°
• 69°+z°=180°
• z°=180°-69°
• z°=111°

Answer 2

12x-63= 7x-8 ,,, 5x= 63-8=55 ,,, x=11

7x-8= 77-8=69

z= 180-69= 111
