Find the value of x and the measure of each angle in the parallelogram

Morgarella [4.7K]

Answer:

$\angle D= 162\\\\\angle E = 18\\\\\angle F = 162\\\\\angle G = 18$

Step-by-step explanation:

By properties of parallelograms we know that opposite are the same so we have

$12x=4(x+3)\\\\4(3x)=4(x+3)\\\\3x=x+3\\\\2x=3\\\\x=\frac{3}{2}$

so for the angles we have

$\angle G=\angle E=12(\frac{3}{2})=18\\\\\angle D=\angle F = 180-\angle G=180-18=162$

Mashutka [201]

Answer:

Two trapezoids labeled V R A S and B U W D. Sides B U and V R contain one tick mark. Sides B D, U W, V S, and R A each contain two tick marks. Sides A S and W D each contain three tick marks. The angles represented by vertex letters U, B, R, and V each contain two tick marks. The angles represented by vertex letters D, W, S, and A each contain one tick mark.

If f(x)=7x-3 and g(x)=x^2-4x, find (f+g)(x).

mote1985 [20]

(f+g)(x) is equivalent to f(x) + g(x)

So that would be (7x-3) + (x²-4x) = x² + 7x - 4x - 3 = x² + 3x - 3

Hope this helps.

The graph of a linear function intersects with the x axis at a point with an abscissa of 4 and with the y axis at a point with a

Leni [432]

We know that

points are
x intercept
A (4,0)

y intercept
B (0,11)

step 1
find the equation of a line
m=(y2-y1)/(x2-x1)--------> m=(11-0)/(0-4)------> m=-11/4

with m and the point B (0,11)
y-y1=m*(x-x1)
y-11=(-11/4)*(x-0)---------> y=-(11/4)x+11

the answer is
<span>the formula of the function is
</span>y=-(11/4)x+11

see the attached figure
