How many solutions does 0.75(x+40)=0.35(x+20)+0.35(x+20) have?

Neporo4naja [7]

Only one because there is one variable and the combined coefficients of x are non-zero.
(0.75(x+40)=0.70(x+20), 0.05x=14-30=-16, x=-320)

What is the length of AC¯¯¯¯¯

Nutka1998 [239]

Answer: AC=12 cm

Step-by-step explanation:

To solve this problem you must apply the law of sines, as you can see below:

$\frac{a}{sinA}=\frac{b}{sinB}$

Where:

a=13

A=85.2°

B=71.6°

Therefore, you must solve for b, then, you obtain that the lenght AC asked in the problem above is:

$b={sinB}*\frac{a}{sinA}\\b=\frac{sin(71.6)*13}{sin(85.2)}\\b=12$
