Answer:

$\sqrt{29}$

Step-by-step explanation:

Use the distance formula!

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

If we plug in the coordinates:

$d=\sqrt{(3-(-2))^2+(4-2)^2} \\d=\sqrt{25+4}\\ d=\sqrt{29}$

That's our answer!

PLSSSSS HELP!!!!!!!!!

Anna11 [10]

Answer:

x=30º

∠CAB=60°

∠ACB=80°

Step-by-step explanation:

Because the angles of every triangle add up to 180º, we know that:

$2x+20+2x=180-40\\ 4x=180-40-20\\ 4x=180-60\\ 4x=120\\ x=\frac{120}{4}$

x=30º

Plug that in for x on both angles, and you will get

∠CAB=60°

∠ACB=80°
