What is the measure of angle K? 102o 118o 134o 156o
stealth61 [152]

Answer:

The measure of angle K is 118°

Step-by-step explanation:

The sum of the internal angles of a quadrilateral is 360°. So, in this case, we can formulate the following equation:

K + L + M + J = 360°

Where K, L, M, and J represent the measure of the angle K, L, M and J respectively.

From the figure we know that: L is 46°, M is 118° and J is 78°. Replacing these values on the initial equation and solving for K we get:

K + 46° + 118° + 78° = 360°

K + 242° = 360°

K = 360° - 242°

K = 118°

So, the measure of angle K is 118°

Hope this helps :)

7. If the area of a square is 64 square centimeters, what's the
Anvisha [2.4K]

Answer:

If you're asking what the perimeter is:

C 32cm

If you're asking what the length of a side is:

A 8cm

Step-by-step explanation:

Area of a square is calculated by length x width.

And all four sides of a square are equal in length.

Area: 8cm×8cm=64cm2

Perimeter: 8cm + 8cm + 8cm + 8cm= 32cm

Another way to find the length of the sides would be to take the square root of 64. I believe that only works with the area of a square though.

√(64)=8
