First you need to multiple minus in second bracket, also in other side you need to multiple - 3 in bracket

Final answer is 0
Given:

To find:
The missing value of m.
Solution:
We have,

Corresponding parts of similar triangles are proportional.

Putting the given values, we get


Multiply both sides by 10.


Therefore, the value of m is 5.
20/10 as a mixed number:
20 ÷ 10 = 2.
10 goes into 20 two times. So 20/10 as a mixed number is a whole number: 2.
20/10 = 2
Answer:

Step-by-step explanation:
We know that,
The sum of interior angles of a triangle is 180 degrees.
So,
2x + 4 + 2x - 9 + x = 180
5x - 5 = 180
Add 5 to both sides
5x = 180 + 5
5x = 185
Divide both sides by 5
x = 185 / 5
x = 37
