Answer:
$25.5
Step-by-step explanation:
12.75 divided into 3 is 4.25 and then 4.25 times 6 gives you 25.5
The length of that arc is (90/360)·2·π·6 = (1/4)·12·π = 3·π ≈ 9.42 units;
Use the formula: A= (a+b/2)h
A=(8+5/2)6
A=39
The answer is the light blue box, 39cm^2
The angle next to the angle 5x is 180 - 5x
All angles sum to 360
(6x - 58) + (2x + 4) + (180 - 5x) = 180
3x + 126 = 180
3x = 54
x = 18
For question 10, sum of angles in pentagon is 540 degrees
x + 105 + 85 + 114 + 126 = 540
x + 430 = 540
x = 110
Answer:
x=8.3 y=16.1
Step-by-step explanation:
87+12y+-7=180
29+9x+6=180
just add like terms then solve
