Find the length of the line segment shown. Round your answer to the nearest tenth.

Marina86 [1]

Answer:

$d=10$

Step-by-step explanation:

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

Step 1: Define endpoint coordinates

(2, 5)

(-6, -1)

Step 2: Substitute and Evaluate

$d=\sqrt{(-6-2)^2+(-1-5)^2}$

$d=\sqrt{(-8)^2+(-6)^2}$

$d=\sqrt{64+36}$

$d=\sqrt{100}$

$d=10$

What is mMHJ? A) 35° B) 50° C) 72.5° D) 92.5°

larisa [96]

∠MHJ and ∠LHK are vertical angles, so:

$mMHJ=mLHK\\\\2x-20=x+15\\\\2x-x=15+20\\\\\boxed{x=35}$

and

$mMHJ=(2x-20)^\circ=(2\cdot35-20)^\circ=(70-20)^\circ=\boxed{50^\circ}$
