Answer:
12.5%
Step-by-step explanation:
105 over 120 is the fraction that he got so you subtract 105 from 120 to get how much he missed. 120-105=15
He miscalculated by 15 cm out of the total of 120, 15/ 120
15/120=5/40=2.5/20 multiply the top and bottom by 5 to get the percentage out of 100. 2.5 times 5 =12.5, so he miscalculated by 12.5%

Answer:
x = 90°
Step-by-step explanation:
Given
- 4 - 6cosx = - 4 - 4cosx ( add 4cosx to both sides )
- 4 - 2cosx = - 4 ( add 4 to both sides )
- 2cosx = 0, hence
cosx = 0
x = 
(0) = 90° for 0 ≤ x ≤ 180
