4)90°-50°=40°
Step-by-step explanation:
5)angle DEC=50°(VERTICAL OPPOSITE ANGLE)
x=50°-15°=35°
6)Y+30°+50°=180°(linear pair)

Answer:
$98.4.
Step-by-step explanation:
Since the university has decided that for the following year lecture costs will increase by 20%, workshop costs by 10%, and examination costs will stay the same, and that for level 2 the current hourly costs are 10, 24, and 60 respectively To determine how much the level 2 course cost in the following year, the following calculation must be performed:
10 x 1.2 + 24 x 1.1 + 60 = X
12 + 26.4 + 60 = X
98.4 = X
Thus, the level 2 course will cost $ 98.4 next year.
