Answer:
No solutions
Step-by-step explanation:

Substitute 3^x with t and we get.

B) An example..... It would be better to explain and give an example to what your trying to say.
The question provides the measures of two angles, (one of which contains
a variable), and the relationship between the angles.
The value of <em>x</em> is <u>6 degrees</u>
Reason:
The given parameters are;
The base angles of the isosceles triangles are; 61° and (7·x + 19)°
Required:
To find the value of <em>x</em>
<em />
Solution:
By definition of an isosceles triangle, we have;
The base angles of an isosceles triangle are equal, therefore;
(7·x + 19) = 61
Which gives;

The value of<u> </u><u><em>x</em></u><u> = 6</u>

Divide both sides by -5 to get x= -13
X^2 + 4x + 4
(x + 2)(x + 2) or (x + 2)^2
