7 0

Answer:

50

Step-by-step explanation:

12x + 15 = 5x +  85   {Subtract 15 from both sides}

12x + 15 - 15 = 5x + 85 - 15  

          12x = 5x + 70        {Subtract 5x from both sides}

12x - 5x   = 70

         7x = 70         {Divide both sides by 7}

          x = 70/7

x = 10

∠U = 5x = 5*10 = 50

Please help<br> Find the area in square units of ABC△ plotted below.
neonofarm [45]

Answer:

Use the distance formula on both points AC and AB.

<em>Distance formula is this</em><em>:</em>

<em>\begin{gathered}d=\sqrt{(x2-x1)^2+(y2-y1)^2} \\\\d=\sqrt{(1--5)^2+(8--7)^2} \\\\d=\sqrt{(6)^2+(15)^2} \\\\d=\sqrt{36+225} \\\\d=\sqrt{261} \\\\\end{gathered}d=(x2−x1)2+(y2−y1)2d=(1−−5)2+(8−−7)2d=(6)2+(15)2d=36+225d=261</em>

Distance for AC  is  16.16

Now do the same with the numbers for AB and get the distance of 5.39

2. To get the area, use the formula 1/2 x base x height

AB is the base and AC is the height.

1/2 x 16.16 x 5.39 = 43.55

the answer is 43.5
