Answer:
8/5
Step-by-step explanation:
(y2-y1) / (x2-x1)
10-2 = 8
8-3 = 5
8/5
Answer:
56.6m
Step-by-step explanation:
Using SOH = opp/hyp
Where θ = 45°
Hpy = 80m
Opp = ?
Sin θ = opp/hpy
Sin 45 = opp/ 80
Sin 45 × 80 = opp
0.7071 × 80 = opp
Opp = 56.568
~ 56.6m
Hence the height of the top of the tree is 56.6m
Area of a sector (A) with a central angle (€) of 5π/7 radians and a diameter of 5.6 in.
Use 3.14 for π, radius (r) = d/2 = 5.6/2 = 2.8in.
A = (€ radians/2π radians)•π r^2
A = (5π7 radians/2π radians)•π (2.8in)^2
A = 5/14•π 7.84 in^2
A = 0.357•3.14•7.84 in^2
A = 8.79 in^2
Length of side b = 12
By doing 15 / 10, we can find how much the right triangle has been reduced compared to the left triangle. So, it’s been reduced by 0.5
Because we’re trying to find side b which is on the larger (left) triangle, we do 8 x 1.5 which is 12
Answer:
40 in
Step-by-step explanation:
A= l x w
2 x 9 = 18
2 x 11 = 22
Then add together because the shape is together:
18 + 22 =
40
