Answer:
The length of other base is <u>30 in</u>.
Step-by-step explanation:
Given:
A trapezoid has an area of 184 in^2. The height is 8 in and the length of one base is 16 in.
Now, to get the length of other base.
Let the length of other base be
Area of trapezoid = 184 in².
Height of trapezoid () = 8 in.
Length of one base (a) = 16 in.
Now, to get the length of other base of trapezoid we solve an equation:
<em /><em />
<em>Subtracting both sides by 64 we get:</em>
<em /><em />
<em>Dividing both sides by 4 we get:</em>
Therefore, the length of other base is 30 in.
Answer:
First number (x) = 12
Second number (y) = 80
Third number (z) = 20
Step-by-step explanation:
Let assume x,y,z to represent first, second and third respectively.
X + y + z = 112
Y = 4z
X = z - 8
So therefore
(Z-8) + (4z) + z = 112
Z + 4z + z = 112 + 8
6z = 120
Z = 120/6
Z = 20.
So,
First x = z - 8
20 - 8 = 12
Second y = 4z
4 x 20 = 80
Third z = 20

Answer:
17
Step-by-step explanation:
The two base angles are congruent, so we have ...
x +17 = 4x -34
51 = 3x . . . . . . . add 34-x
17 = x . . . . . . . . .divide by 3
1.7x 10 =17
