Answer:
y=-x+4
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(2-3)/(2-1)
m=-1/1
m=-1
y-y1=m(x-x1)
y-3=-1(x-1)
y-3=-x+1
y=-x+1+3
y=-x+4
1+179=180 2+178=180 3+177=180 4+176=180 5+175=180 6+174=180.............theres a lot of answers do u want every single one
The area of a triangle formula is A = 0.5*b*h where b is the base and h is the height. To solve for b, we multiply both sides by 2 to get 2A = b*h and then we divide both sides by h to get b = 2A/h. Now plug in the given info to get...
b = 2*A/h
b = 2*36/6
B = 72/6
b = 12
so if the area is 36 and the height is 6, then the the base must be 12
Answer:
1260 cm^2
Step-by-step explanation:
To find the area of the rectangle we need its base and its height and calculate the product A = (base)(height).
Here the height of the triangle is found using the Pythagorean Theorem:
37^2 = |AB|^2 + 12^2, or |AB|^2 = 1369 - 144, or 1225.
Taking the square root of both sides, we get |AB| = √1225 = 35 cm = height of rectangle.
Since BC:CD = 1:2, and since |BC| = 12 cm, |BD| is 12 cm + 24 cm = 36 cm.
Thus the length of the rectangle is 36 cm.
The area of the rectangle ABDE is (36 cm)(35 cm) = 1260 cm^2
