Answer:
Step-by-step explanation:
23 inches
The equation can be modeled as
X + X + (X+4) = 61
X is used for all because they are all the same number and can be given the same variable
The third is given plus four so we can use a common variable
3x + 4 = 61
3x = 57 (subtracted four)
x = 19 (divided by three)
Solving for third side so x + 4
The third side is 23 inches
E
because it makes sense
D is the distance from moon to sun, and it's the hypotenuse of a right triangle.
Y is opposit to angle X
Sin (x) = y/d =
D = Y/sin(x)
y=-7x+9
AREA OF TRAINGLE =18
WE NO THE AREA OF 1/2 BH
B=6
PLUGGING IN THE VALUES
18 1/2 6 (H+1)
6=H+1
H=5
