Answer number 1 please.​

\sf {a}^{2}  =  {13}^{2}  -  {5}^{2}

Formula :

Base²= Hypotenuse² - Perpendicular ²

\\  \\

\hookrightarrow\sf {a}^{2}  =  {13}^{2}  -  {5}^{2}

\\  \\

\hookrightarrow\sf {a}^{2}  =169 - 25

\\  \\

\hookrightarrow\sf {a}^{2}  =144

\\  \\

\hookrightarrow\sf {a} = \sqrt{144}

\\  \\

\hookrightarrow\sf {a} = \sqrt{12 \times 12}

\\  \\

\hookrightarrow\sf {a} = 12

Remember the a² in formula has nothing to do with the a we have to find. :)

Find the measure of each exterior angle.
devlian [24]

Answer:

The answer is 137 degrees

Step-by-step explanation:

Add up the two angles you know already

93 + 44 = 137

Then you take that number and subtract it from 180 in order to find the other interior angle.

180 - 137 = 43

So angle LKJ is 43 degree

Now to find the exterior angle you take the missing angles measurement

Which is 43 and subtract it from 180 to get 137

60 inches since there is 2 inches of snow for 3 days, so that equals 6 inches for 3 days and then you just have to multiply 6 by 10 and you get 60 inches of snow, or 5 feet
