Answer:
14.4cm
Step-by-step explanation:
Let the 7th length be y
Mean of the length = sum of all the length/number of let
Mean of the length = 13cm
13 = (11.8 + 12.4 + 12.5 + 13.2 + 13.6 + 13.1 + y) /7
13 = (76.6 + y) /7
Cross multiply to express in linear form
13 x 7 = 76.6 + y
91 = 76.6 + y
Collect like terms
91 — 76.6 = y
y = 14.4cm
Therefore, the 7th length is 14.4cm

Answer:
The rays must have a common endpoint
Step-by-step explanation:
An angle is basically a figure that is formed when two rays share a common endpoint or vertex. The term angle comes from the Latin word "angulus" which means "corner". If you look at an angle, you will see a corner formed between the two rays.
Answer:
186 cm²
Step-by-step explanation:
<em>*First we can move the shape around a bit to make it simpler to solve. If we take the triangle from the left side and move it over to the right, it connects with the other piece to create a rectangle. This leave two rectangles total which is much easier to solve.</em>
<em>*To find the length of the right rectangle, you take the 22 cm at the bottom and subtract the 12 cm (which is being used as the length for the left rectangle). This will give you a length of 10 cm long.</em>
<u>Left rectangle:</u>
A = lh
A = 12 (8)
A = 96 cm²
<u>Right rectangle:</u>
A = lh
A = 10 (9)
A = 90 cm²
<u>Total:</u>
A = 90 + 96
A = 186 cm²
