Answer: 14.4

Step-by-step explanation: To find the third side of the triangle, we have to use the pythagorean theorem...

a² + b² = c²

a² + 4² = 15²

a² + 16 = 225

225 - 16 = 209

$\sqrt{209}$

a ≈ 14.4 (If rounded it would be 14)

I hope this helps!

2+2=4

a^2+b^2=c^2
15^2-4^2
=225-16
=209

In ABC, BC=4 cm, angle b=angle c, and angle a=20 degrees, what is ac to two decimal places

zubka84 [21]

Answer:

Therefore,

$AC=11.52\ cm$

Step-by-step explanation:

Given:

In ΔABC, BC=4 cm,

angle b=angle c, and

angle a=20°

To Find:;

AC = ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

$\angle a+\angle b+\angle c=180\\\therefore 2m\angle b =180-20=160\\m\angle b=\dfrac{160}{2}=80\°$

We know in a Triangle Sine Rule Says that,

In Δ ABC,

$\dfrac{a}{\sin A}= \dfrac{b}{\sin b}= \dfrac{c}{\sin C}$

substituting the given values we get

$\dfrac{BC}{\sin a}= \dfrac{AC}{\sin b}$

$\dfrac{4}{\sin 20}= \dfrac{AC}{\sin 80}\\\\AC=11.517=11.52\ cm$

Therefore,

$AC=11.52\ cm$

I GIVE BRAINLIEST 4(3x + 1) = 12x + 4 show work pls!!

mixer [17]

Answer:any number is correct

Step-by-step explanation:

4(3x+1)=12x+4

12x+4=12x+4

12x-12x=4-4

0=0

This equation has no answer.

Actually any number you put in place of x this equation will be true so we can say the answer is

X=infinity
