PLS ANSWER RN<br><br> What is the area of AJKL?
alex41 [277]

Answer:

8.5

Step-by-step explanation:

slope of the line that contains KL

(y2 - y1)/(x2-x1)

(0-1)/(7-3)

m = -1/4

slope of the line that contains JK

(5-1)/(4-3)

m = 4

the linea are perpendicular so triangle is right

area = (leg1 x leg2)/2

KL = \sqrt{(7-3)^2 + (0-1)^2} = \sqrt{16 + 1} = \sqrt{17}

KJ = \sqrt{(4-3)^2 + (5-1)^2}= \sqrt{1 + 16} = \sqrt{17}

area = (√17)^2/2 = 17/2 = 8.5

The angle marked a = 120°.<br> Work out the value of x.<br><br> The diagram is not drawn accurately.
lapo4ka [179]
<h3>Answer:  x = 60</h3>

Work Shown:

a+x = 180

120+x = 180

x = 180-120

x = 60

Side note: angles 'a' and x are same side interior angles, which are supplementary whenever we have parallel lines like this.

I don't know which one is the correct answer? PLEASE HELP!!​
alukav5142 [94]
The answer is 1/q^30 because after simplifying, you can cancel out the p and then you get q^q-20 times q^-10 to get q^-30 which then equals 1/q^30
