Answer: 7i
explanation: √-1 is i because a negative square root is imaginary. you can take out the negative from the inside of the square root and replace it with i on the outside. that leaves you with √49, which is 7, and that gives you 7i
KJL and NJM are both adjacent to MJL
Answer:
x = 6; measure of each side 83
Step-by-step explanation:
<em>Equilateral Triangle means all sides are equal length</em>
Knowing this, you can set up the following equation:
<u><em>2(JK/KL/JL) = 2(JK/KL/JL)</em></u> <all lines are interchangeable in the equation as long as they are not the same on both sides>
2(13x+5) = 2(17x-19)
26x+10 = 34x-38
x = 6
<em>Plug in the variable:</em>
13(<u>6</u>) + 5 = 83
17(<u>6</u>) - 19 = 83
8(<u>6</u>) + 35 = 83
