Find the value of X.
Oksanka [162]

Answer:

x =25

Step-by-step explanation:

This is an isosceles triangle because RS = ST

that means <r = <STR

4x-70 = STR

<STR + <STU = 180   straight line

subtract < STU from each side

<STR = 180 -<STU

we know angle stu = 6x

<STR = 180 -6x

we can substitute this into 4x-70 = STR

4x-70 = 180 -6x

add 6x to each side

4x+6x -70 = 180 -6x+6x

10x -70 = 180

add 70 to each side

10x-70+70 = 180+70

10x=250

divide by 10

10x/10 = 250/10

x =25

See attachment for the number line that compares the numbers 5.3, 5 1/5 and 5

<h3>How to plot the numbers on the number line?</h3>

The numbers are given as:

5.3, 5 1/5 and 5

We start by representing the numbers as decimals (i.e. real numbers).

So, we have:

5.3, 5.2 and 5

Reorder the numbers in ascending number (i.e. from least to greatest)

So, we have

5, 5.2 and 5.3

Next, we plot the numbers on a number line using a scale of 0.1

This can be visualized as

5        5.2      5.3

See attachment for the number line that compares the numbers 5.3, 5 1/5 and 5
