In ΔMNO, the measure of ∠O=90°, MO = 15, ON = 8, and NM = 17. What ratio represents the cosine of ∠N?

Nesterboy [21]

Answer: The required ratio would be $8:17.$

Step-by-step explanation:

Since we have given that

∠O=90°,

MO = 15, (Perpendicular)

ON = 8, (Base) and

NM = 17 (Hypotenuse)

So, we need to find the cosine of ∠N.

As we know that

$\cos N=\dfrac{Base}{Hypotenuse}\\\\\cos N=\dfrac{8}{17}$

Hence, the required ratio would be $8:17.$

a(x+b)=4x+10 in the equation above a and b are constants. if the equation has infinitely many solutions for X, what is the value

xeze [42]

Answer:

$b= \frac{5}{2}$

Step-by-step explanation:

Given

$a(x+b)=4x+10\\ax+b= 4x+10\\$

Now we know that system has infinite solution for x

$\frac{a_1}{a_2}=\frac{b_1}{b_2}$

in above equation.

$a_1=a, a_2=4, b_1=ab,b_2=10\\$

∴ $\frac{a}{4}=\frac{ab}{10}\\\therefore b=\frac{10\times a}{4\times a}=\frac{5}{2}$
