Answer:

76 degrees

Step-by-step explanation:

We know that supplementary angles equal 180 degrees. So, set up the equations:

180=(x+15)+(x-13)\\

180=(2x+2)\\

178=2x

x=89\\

Then, you just plug 89 back into ZB, and simplify:

(89-13)\\

=76

So, the measurement of angle ZB is 76 degrees.

- Inessa ran 3 laps in 10 minutes. How long
Anni [7]

Answer: 16 minutes and 40 seconds

Step-by-step explanation:

1.) Divide 10 minutes by 3 laps in order to find out how long it takes her to run a single lap. (it ends up being 3 minutes and 20 seconds per lap)

2.) Multiply this number by 5, you get 16 minutes and 40 seconds.

NOTE: remember that you’re using intervals of 60 (seconds in a minute) rather than intervals of 100.

Quadrilateral JKLM is a rhombus. The diagonals intersect at N. If angle JNK equals 5x - 15, find the value of x.
VLD [36.1K]
One property of a rhombus is that the diagonals are perpendicular. This means that the diagonals intersect at 90 degree angles (right angles).

So we know that angle JNK is 90 degrees

angle JNK = 90 degrees
5x - 15 = 90
5x - 15 + 15 = 90+15
5x = 105
5x/5 = 105/5
x = 21

Answer: x = 21
