Answer:

42 deg, 138 deg

Step-by-step explanation:

Angles of a linear pair are supplementary. That means that their measures have a sum of 180 degrees.

Let the measure of one angle be x.

The other angle is 12° more than three times the first.

The other angle has measure 3x + 12.

The sum of their measures is 180 deg.

x + 3x + 12 = 180

4x + 12 = 180

4x = 168

x = 42

One angle measures 42 deg.

The other angle measures

3x + 12 = 3(42) + 12 = 138

The other angle measures 138 deg.

(4,0) , (-8,0) calculate the distance between the given points
valina [46]

Answer:

12

Step-by-step explanation:

Using formula

distance = \sqrt{ (y2 - y1)^{2}  + (x2- x1)^2}

Then input the values:

Distance = \sqrt{ (0 - 0)^{2}  + (-8- 4)^2}

               = \sqrt{0 + 144}

               = 12

​Together, teammates Pedro and Ricky got 2687 base hits last season. Pedro had 283 more hits than Ricky. How many hits did each
Vaselesa [24]

Answer:

Ricky hits 1202 base

Pedro hits = 1485 base

Step-by-step explanation:

Pedro + Ricky = 2687 hits

Let Ricky hits = x

So the Pedro hits will be = x + 283

( x + 283 ) + x = 2687

2 x + 283 = 2687

2 x = 2687 - 283

2 x = 2404

x = 1202

So the Ricky hits 1202 base

Pedro hits (1202 + 283) = 1485 base
