7 - 9w = - 29
Subtract 7 from both sides
- 9w = - 36
Divide by - 9 on both sides
w = 4

Answer: 
Step-by-step explanation:
To solve this problem you must apply the proccedure shown below;
- Make the equation equal to zero:

-Add 49 at both sides:

- Now, you must take the square root of both sides of the equation, then you obtain the following roots:

- Then you have:


Answer:
<u>See below:</u>
Step-by-step explanation:
Let the angles be 5x , 4x , 3x.[Since the angles are in ratio 5:4:3 ] respectively.
We know that sum of all angles of a triangle is 180°.
So,

Now Find the value of x of this equation.





Now,
Multiply each ratio given by 15 which is the value of x we got.
That is;



Hence,the measurements of the angles of the triangle would be 75°[First Angle],60°[Second angle],and 45° [Third Angle].
