The sum of the three angles is 180. One is given and the other we can figure out because it forms a straight line (180) with the angle to the left outside. The outside angle is 117, so 180-117 is 63.
So then add up the 3 angles in the triangle
63+35+y=180
y= 82

Which value of x is a solution of the inequality 12x-14<61

pochemuha

An inequality is solved by more than one value - usually an interval, or a union of intervals.

In this case, we have:

$12x-14$

Add 14 to both sides:

$12x$

Divide both sides by 12:

$x$

Please find x and a

aev [14]

Answer:

x = 36

a = 25

Step-by-step Explanation

By Pythagoras Theorem:

$x = \sqrt{ {39}^{2} - {15}^{2} } \\ \\ x = \sqrt{1,521 - 225} \\ \\ x = \sqrt{1,296} \\ \\ x = 36 \\ \\ a = \sqrt{ {20}^{2} + {15}^{2} } \\ \\ a = \sqrt{400 + 225} \\ \\ a = 25 \sqrt{625} \\ \\ a = 25$
