Given that the triangle is isosceles, we can say that AB = AC. Using the given expressions we can form the following equation.

\begin{gathered} AB=AC \\ 5x+8=7x-6 \end{gathered}

Let's solve for x.

\begin{gathered} 8+6=7x-5x \\ 14=2x \\ x=\frac{14}{2} \\ x=7 \end{gathered}

Once we have the value of the variable, we can find the length of AC.

\begin{gathered} AC=7x-6 \\ AC=7(7)-6 \\ AC=49-6 \\ AC=43 \end{gathered}<h2>Therefore, the length of AC is 43.</h2>

Two vectors and have the components, in meters, ax = 6.91, ay = 1.45, bx = 2.45, by = 7.02. (a) find the angle between the direc
White raven [17]
We are given
ax = 6.91
ay = 1.45

bx = 2.45
by = 7.02

So,
tan a→ = 1.45/6.91 = 0.2098 = ma
tan b→ = 7.02/2.45 = 2.8653 = mb

To get the angle between the two
tan θ = (mb - ma)/(1 + ma mb)
tan θ = (2.8653 - 0.2098) / (1 + (2.8653) (0.2098) )
θ = 58.91°
The x component is
x = 8.28 cos 58.91 = 4.28 m
The y component is
y = 8.28 sin 58.91 =  7.09 m

What is the simplified form of 3 over 4x plus 3 + 21 over 8 x squared plus 26x plus 15
arsen [322]
This is the concept of algebra, we are required to add up the terms given above, here we shall have:
3/(4x)+21/(8x)+26x+15
when we sum up we get:
27/(8x)+26x+15
=(27+208x^2+120x)/(8x)
The simplified form of the summation of the terms is:
(27+208x^2+120x)/(8x)

Line segment AB has a length of 5 units. It is translated 3 units to the right on a coordinate plane to obtain line segment A pr

5 units long because when you have a translation the length, size and shape of the segment doesn't change it's just moved over on the coordinate plane.
