Use the figure and given angle to find the measure of each angle below (tell me how many degrees it is).

Answer:

∠6 = ∠4 = 84°

∠5 = ∠3 = 96°

Step-by-step explanation:

Angle 4 and the marked angle (84°) are <em>corresponding</em> angles, so are congruent. Angles 4 and 6 are vertical angles, so are congruent.

∠6 = ∠4 = 84°

Angle 3 and the marked angle are a linear pair, so angle 3 is the supplement of 84°:

∠3 = 180° -84° = 96°

Angle 3 and angle 5 are <em>alternate interior </em>angles, so are congruent.

∠5 = ∠3 = 96°

Ryan and Marie had some marbles. if Ryan lost `15 marbles, he would have 4 times as many marbles as Marie. If Ryan lost 75 marbl

vaieri [72.5K]

Ryan's marbles = x
Marie has 4 times less marbles then Ryan would have if he lost 15 marbles (it means he would have x-15)
So, Marie marbles = (x-15):4
If Ryan lost 75 marbles (it means he would have x-75), he would have 1 1/2 times as many marbles as Marie.

We got an equation: $x-75=1\frac{1}2\cdot\frac{x-15}{4}$

          $x-75=\frac{3}2\cdot\frac{x-15}{4}$

Multiply both sides by 8:     $8x-8\cdot75=3\cdot(x-15)$

      $8x-600=3x-45$

Add 600 and subtract 3x on both sides:    $5x=555$

Divide both sides by 5:    $x=111$

Answer: Ryan have 111 marbles.

a triangle has angles measuring 45°, 55°, and 80°. it is dilated by a scale factor of 2. what are the angle measures, in order f

EastWind [94]

Answer:

$45$ °, $55$ °, and $80$ °

Step-by-step explanation:

Dilations preserve angle measures, regardless of the scale factor. Therefore, the angle measures of the image will be the same of that of the pre-image, so our answer is still $45$ °, $55$ °, and $80$ °. Hope this helps!
