Determine the value of x.​

Mathematics
1 answer:
telo118 [61]3 years ago
5 0

Answer:

10

Step-by-step explanation:

This triangle is isosceles, same as the little triangle.

If one side of the little triangle is 3x, then the little side with the tick (let's name it a) is also 3x.

That means the longer side, 2a, is 6x

This triangle is isosceles, so 6x = 4x + 20

Now, if we solve that, x = 10

The answer is 10

Hope this helps :)

Have a good day!

MrRissso [65]
Given that we assume that all the bases of the triangles are parallel.

We can use AAA or Angle-Angle-Angle to prove that these triangles are similar.

Each parallel line creates the same angle when intersecting with the same side.
For example:
The bases of each triangle cross the left side of all the triangle.
Each angle made by the intersecting of the the parallel base and the side are the same.
Thus, each corresponding angle of all the triangles are congruent.
If these angles are congruent, then we have similar triangles.

Can someone pls tell me how to graph to find the solution?​
Bas_tet [7]

Answer:

Rearrange the equation so "y" is on the left and everything else on the right.

Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).

Step-by-step explanation:

sorry if wrong

Find the area of the parallelogram shown below.60 squ
ArbitrLikvidat [17]

Answer:

A

Step-by-step explanation:

The area for a parallelogram is given by the formula:

A=bh

Where b is the base length and h is the vertical height.

The base length is 6 and the height is 10 (if you flip the figure 90 degrees). So:

A=6(10)

Multiply:

A=60\text{ units}^2

Our answer is A.

And we're done!
