Answer:

No. It has 2 congruent triangles, but they do not encompass the whole area.

Step-by-step explanation:

I would say no, because then it would be a rectangle, because there would be no angle on the sides.

A=1/2(b1+b2)*h

Answer:

KM=41.6

Step-by-step explanation:

$\frac{HJ}{IJ} =\frac{KM}{ML} \\\frac{8}{6} =\frac{KM}{31.2} \\$

Cross Multiply and Solve for KM.

$6*KM=8*31.2\\KM=\frac{8*31.2}{6} \\KM=41.6$

The Knicks and Nets have a total 30 players.

Blababa [14]

Answer:

Step-by-step explanation:

From the problem statement, we can set up the following two equations:

$K + N = 30$

$20K + 10N = 500$

where $K$ is the number of Knicks players, and $N$ is the number of Nets players.

We can substitute the first equation into the second and solve for $K$

$K + N = 30$

$N = 30 - K$

$20K + 10N = 500$

$20K + 10(30 - K) = 500$

$20K + 300 - 10K = 500$

$10K + 300 = 500$

$10K = 200$

$K = 20$

A party tent is used for an outdoor event. Ropes of equal length support each tent pole. The angle the rope makes with the floor

Virty [35]

Law of sines can be used to solve this problem:

(note - let x represent the missing side length.)

1. set up proportion.
sin 90°/25 = sin 55°/x

2. solve.
(x) sin 90° = (25) sin 55°

(x) sin 90 °/sin 90° = (25) sin 55° / sin 90°

x = 20.4788011072
rounded to nearest tenth = 20.5
