Answer:
Step-by-step explanation:
- <em>Sum of exterior angles of any polygon is 360°</em>
<h3>Exercise 8</h3>
<u>Sum of given angles:</u>
- 2x + 60° + 64° + 36° + 48° = 360°
- 2x + 208° = 360°
- 2x = 360° - 208°
- 2x = 152°
- x = 76°
<h3>Exercise 9</h3>
<u>Sum of given angles:</u>
- x + 90° + 109°+ 73° = 360°
- x + 272° = 360°
- x = 360° - 272°
- x = 88°
Answer:
literally google graphing calculator and type 3x
Answer:
12800
Step-by-step explanation:
(8 * 8 * 8) * (5 * 5)
512 * 25
12800
The answer is 4. 2x plus 7 is equal to 15. First you subtract 7 from both sides then divide by 2 to get the answer 4. Hope this helps!
