Answer:
a = 50°, b = 130°, c = 20°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles in the right triangle
a + 40° + 90° = 180°
a + 130° = 180° ( subtract 130° from both sides )
a = 50°
a and b are adjacent angles and sum to 180° , so
a + b = 180°
50° + b = 180° ( subtract 50° from both sides )
b = 130°
Then sum the angles in the top triangle, that is
30° + 130° + c = 180°
160° + c = 180° ( subtract 160° from both sides )
c = 20°
Answer:
1.75 feet
Step-by-step explanation:
48 ÷ 2 = 14
14 ÷ 2 = 7
7 ÷ 2 = 3.5
3.5 ÷ 2 = 1.75

75%=75/100=75:100=3/4
4-3=1
1/4=tables not used.
1/4=25/100=25:100
So....25:75 = not used tables : used tables
Hoped I helped!
