Answer:
The answer is below
Step-by-step explanation:
AD = X + 8 ∠D = 2y +13 ∠C = 16 - x CB = 5y+4
In a parallelogram, consecutive angles are supplementary and opposite sides are equal.
Therefore for parallelogram ABCD, AB = CD, CB = AD
Since AD = CB (opposite sides of a parallelogram are equal):
x + 8 = 5y + 4
5y - x = 8 - 4
5y - x = 4 (1)
∠C + ∠D= 180° (consecutive angles of a parallelogram are supplementary). Therefore:
16 - x + 2y + 13 = 180
2y - x + 29 = 180
2y - x = 180 -29
2y - x = 151 (2)
To find x and y, subtract equation 1 from equation 2:
3y = -147
y = -49
Put y = -49 in equation 2
2(-49) - x = 151
x = -98 - 151
x = -249
The answer is t=4 hope it right
Answer:
The height is 35 inches
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
We know the area is 245 and the base is 14
245 = 1/2 (14)*h
245 = 7h
Divide each side by 7
245/7 =7h/7
35 =h
The height is 35 inches
Yes
Plug in the x and y
(2*9)+(4*-3)= 18-12= 6
(6*9)+(14*-3)= 54-42= 12
