Fill in the blank. (5x)2 a0x2

Yuki888 [10]

Answer: $a_0=25$

Step-by-step explanation:

It is given that, $(5x)^2=a_0x^2$

We need to find the value of $a_0$

As $(5x)^2=a_0x^2$

Solving LHS

$25x^2=a_0x^2$

Now comparing the coefficients of $x^2$

In LHS the coefficient of $x^2$ is 25

In RHS the coefficient of $x^2$ is $a_0$

It implies that, $a_0=25$

So, the value of $a_0$ is 25.

Triangle ABC is similar to triangle LMN by the similarity postulate

likoan [24]

Answer:

Same as Angle B. 90 degrees.

Step-by-step explanation:

If triangles are similar then they have the exact same angle measures. Angle m will have the same value as angle B. If angle B's measure is not found, then find it by adding angle A and angle C together and subtract from 180.

The picture is cut off but if A =60 and C=30 then 60+30=90 and 180-90=90. Angle B and M are both 90 degrees.

Help me solve this. Please, it's math.(I suck at math ngl ︺︹︺ )

fredd [130]

Answer:

Vertical angles are congruent, so the

equation 3x-6 = 114 can be used to find x.

The value of x is 40.

Convince Me!

Why can you use an equation when solving for x in

the diagram?

You can use the eqution because they are equal to each other. When they are equal to each other, you can find x by using the equation to simplify and get x alone.
