Since they are the angles of the triangle they should add up to 180.

angle R + angle S + angle T = 180

2x + 10 + 2x + 25 + x - 5 = 180

Combine like terms:

5x + 30 = 180
5x = 150
x = 30

SO the value of x is 30

Hope this helps :)

In a triangle, the three interior angles always add to 180°

m∠R + m∠S + m∠<span>T = 180

</span><span>(2x+10) + (2x+25) + (x-5) = 180
</span>2x+10 + 2x+25 + x-5 = 180
5x + 30 = 180
5x = 150
x = 30

Help on 20, would be appreciated if there was a explanation as well
ra1l [238]
For a two column proof, we want to start with the given information. From there, we will use various definitions, postulates, and theorems to fill in the rest.

Our two sets of given information are that Plane <em>M </em>bisects Line <em>AB </em>and that Line <em>PA</em> is congruent to Line <em>PB</em>.

We know from the definition of a bisector that it splits a line in two equal parts. Therefore, Line <em>AO</em> must be congruent to Line <em>BO</em>.

Now, we have two sides of a triangle that we have proved to be congruent to each other. From the image given in the original problem, we see that both triangles share Line <em>OP. </em>Line <em>OP</em> is congruent to Line <em>OP</em> through the reflexive property.

We now have proven that all three sides of the one triangle are congruent to the corresponding sides on the other triangle. Therefore, the triangles are congruent through the SSS theorem.

Im so confused- please help
Orlov [11]

Step-by-step explanation:

a/q

x + x - 3 + 2x - 9 = 36

4x - 12 = 36

4x = 36 + 12 = 48

x = 48/4 = 12

x = 12

so,

x = 12

x - 3 = 12 - 3 = 9

2x - 9 = 2(12) - 9 = 15

we know,

area = 1/2 × base × height

so,

→ 1/2 × 12 × 9

→ 1 × 6 × 9

→ 54 inches.

Solve <br> 2x-10=2 6 for x
strojnjashka [21]

Answer:

x=18

Step-by-step explanation:

isolate x to one side of the equation:

2x=26+10

2x = 36

divide by 2 for both sides

x = 36\2

x= 18

One number is three times another number. If the sum of the numbers is 36, determine the two
Svetllana [295]

Answer: biggest no.=27. Smallest number=9

Step-by-step explanation:

Let's take the smallest number as x and the biggest number as 3x since it is 3 times bigger than x.

The sum of these two numbers is 36

3x+x=36

4x=36

X( smallest number)=36/4: 9

While, the biggest number is 3x: 3×9=27
