Answer:
b=-10
c=25
Step-by-step explanation:
if the only solution is 5 so
x^2+bx+c=(x-5)²=x²-10x+25
b=-10
c=25
For the given quadratic equation [tex]x^{2} +b x + c=0[/tex] value of 'b' = -10 and value of 'c' = 25.
What is quadratic equation?" Quadratic equation are defined as the algebraic equation in which highest exponent of the variable is two. General form of quadratic equation is [tex]ax^{2} + bx + c=0[/tex] where a≠0."
According to the question,
Given quadratic equation is,
[tex]x^{2} +b x + c=0[/tex] ______(1)
Solution of the given quadratic equation x = 5.
From this we have,
[tex]x-5=0\\\\(x-5)^{2} =0[/tex] _____(2)
Equate equation (1) and (2) to get the value of 'b' and 'c' ,
[tex]x^{2} +b x + c=(x-5)^{2}[/tex]
⇒[tex]x^{2} +b x + c= x^{2} -10 x + 25[/tex]
Compare Left hand side and right hand side we get,
b = -10
c = 25
Hence, for quadratic equation [tex]x^{2} +b x + c=0[/tex] value of 'b' = -10 and value of 'c' = 25.

En un triángulo, dos de sus ángulos internos miden 40º y 55º. Hallar la medida de su tercer ángulo interno.
Answer:
La medida del tercer ángulo interno es 85°.
Step-by-step explanation:
Los triángulos son figuras geométricas planas que poseen tres lados en contacto entre sí en puntos comunes denominados vértices. A su vez, los triángulos poseen tres ángulos interiores. Estos tres ángulos interiores del triángulo suman 180°.
En este caso, en un triángulo, dos de sus ángulos internos miden 40º y 55º. Siendo θ el tercer ángulo interior, entonces:
θ + 40° + 55°= 180°
Resolviendo:
θ + 95°= 180°
θ= 180° - 95°
θ=85°
La medida del tercer ángulo interno es 85°.
