Answer:
The measure of angle A is 115°
Step-by-step explanation:
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
∠C+∠A+∠B=180°
substitute values and solve for x
x°+(3x-35)°+(x-35)°=180°
5x°=180°+70°
x=250°/5=50°
Find the measure of angle A
∠A=(3x-35)°
substitute the value of x
∠A=(3(50)-35)=115°
 
        
                    
             
        
        
        
Divide each side by 16
x = 3
        
                    
             
        
        
        
Answer:

What is the degree of polynomial?

The degree of a polynomial is the highest of the degrees of the polynomial's monomials with non-zero coefficients.
Example:

4x The Degree is 1 (a variable without an
exponent actually has an exponent of 1)
 More Examples:
4x^ − x + 3 The Degree is 3 (largest exponent of x)
 
x^2 + 2x^5 − x The Degree is 5 (largest exponent of x)
 
z^2 − z + 3 The Degree is 2 (largest exponent of z)
A constant polynomials (P(x) = c) has no variables. Since there is no exponent to a variable, therefore the degree is 0.
3 is a polynomial of degree 0.
 
        
                    
             
        
        
        
$14.50 because your equation would be 4+1.50(7)=$14.50.
