Step-by-step explanation:
Since AC = BC then ΔABC is isosceles with base angles
∠BAC =∠ABC, thus
3x + x = 70
4x = 70 ( divide both sides by 4 )
x = 17.5
----------------------------------------------------
∠ADC is an external angle of ΔABD and the external angle is equal to the 2 opposite interior angles, hence
y = 70 + x = 70 + 17.5 = 87.5
Area of the trapezoid=
1/2(b1+b2)×2
A=1/2(8+11)×12
A=1/2(19)×12
A=6×19
A=114 square meters. As a result, the area of the courtyard is 114 square meters. Hope it help!
Answer:
X=-6
Step-by-step explanation:
Subtract 9 on both sides
Add -9 and -15 You get -24
Divide -24 by 4 you get x=-6
Answer:
B. (-3, 2)
Step-by-step explanation:
The solution is given by the coordinates of the point where the lines intersect.
From the graph we see that it is the point where x = -3 and y = 2.
