A. (Number of sides - 2) x 100, so
6-2= 4 x 180
= 720° is the sum of all angles in a hexagon
84 + 87 + 128 + 150 + 103 = 552
720 - 552 = 168
X = 168°
2. Angles in a triangle sum up to 180°
36 + 57= 93
180 - 93 = 87
A= 87°
Answer:
42 ft
Step-by-step explanation:
14 times 14=196
R of circle =7
7 squared=49
49 times pi= 153.938040026
196-153.938040026= 42.0619599741
Rounded to 1 decimal=42.1
Rounded to whole number = 42
Answer:
20
Step-by-step explanation:
Vertical angles are always equal to each other. So the answer is
3x + 4 = 73 - 9 Are you sure this is what the question is?
3x + 4 = 64 Subtract 4 from both sides
<u> -4 -4</u>
3x = 60 Divide by 3
3x/3 = 60/3
x = 20
