Answer:
Step-by-step explanation:
(3, 0) (0, 2)
(2-0)/(0-3) = 2/-3= -2/3
y - 0 = -2/3(x - 3)
y = -2/3x + 2
25% * 35% * 400
25/100 (35) / 100 (400)
1/4 (35) / 100 (400)
35/4 / 100 ( 400)
7/80 (400)
= 35
Step-by-step explanation:
a) barn area = 9 × 9 = 81 m^2
b) perimeter = 9 × 4 = 36m or
= 9+9+9+9 = 36m
Answer:
20.5
Step-by-step explanation:
Let's label the vertices ABC as in the diagram below. Then
Data:
α = 34 °
β = 90 °
c = 17
Calculation:
cosα = AB/AC
Multiply each side by AC
ACcosα = AB
Divide each side by cosα
AC = AB/cosα = 17/cos34 ≈ 17/0.8290 ≈ 20.5
