Answer:
x = 14
Step-by-step explanation:
4x° + (3x + 20)° + (3x + 20)° = 180° (sum of interior angles; isocleces triangle)
10x + 40 = 180
10x = 140
x = 14
Answer:18
Step-by-step explanation:4(-3) = -12, and 40-12=18
The answer would be 4/85
1. 2/5 ÷ 8 * 2 + 1 over 2
2. 2/5 ÷ 16 + 1 over 2
3. 2/5 ÷ 17/2
4. 2/5 * 2/17
5. 2 * 2 over 5 * 17
6. 4 over 5 * 17
7. finally 4/85
