Step-by-step explanation:
So 95 is a linear pair. a linear pair adds up to 180 so 180 - 95 = 85
X = 85
y = 50
A) 20.9
b) (230 + x) / 12 = 22
230 + x = 264
x = 34 years old
Answer:
58.5; 300; 196.5
Step-by-step explanation:
Area of triangle 1 = (1/2) * 9 * 13 = 58.5 inches^2
Area of whole figure = (1/2) * (14+26) * 15 = 300 inches ^2
Area of shaded region = 300 - 58.5 - [(1/2) * 6 * 15] = 241.5 - 45 = 196.5 inches^2
Average = sum of all numbers divided by how many numbers there are. so you do 1+0+1+5+6+3+4/7. this gives you 20/7, which is about 2.857
