Answer:
21 1/3
Step-by-step explanation:
20 ÷ 15/16=
20/1 ÷ 15/16=
20/1*16/15=
4/1*16/3=
64/3=
21 1/3
Step-by-step explanation:
mXYZ+mXYW=180°(being straight angle)
mXYW =180-115
mXYW=65
now,
mXWY+mWXY+mXYW=180°(sum of angle of triangle)
mXWY=180-110
mXWY=70°
hope it helps.
Answer:
19.0
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relationship ...
Cos = Adjacent/Hypotenuse
cos(38°) = 15/w
w = 15/cos(38°) ≈ 19.035
The length of the missing side is about 19.0.

A diagonal connects a vertex to another vertex without being a side of the polygon. There are 14 vertices in a 14-gon. This leaves 13 vertices left to connect to (since we cannot connect the vertex to itself). However, two of these vertices will form the sides of the 14-gon. This leaves us with 11 possible diagonals we can draw.
