Answer:
x= 23 y=88
Step-by-step explanation:
3x+23= 4x
x=23
x and y are supplementary angles so they add up to 180 so then if x is 23
23 x 4= 92
so 180-92 is 88
therefore y is 88 and x is 23
Divide the nonagon radially into 9 congruent, equilateral isosceles triangle. Each triangle has vertex angle of 360°/9 = 40°.
Interior angle of polygon = 180°-40° = 140°.
Sum of interior angles = 9(140°) = 1260°
Answer:
$159.95
Step-by-step explanation:
Let price of trumphet be defined by
price of clarinet = $139.95
Number of clarinets sold = 19
Earning through clarinets' sale =
Total earning of store = $4578.45
Earning through trumphets' sale =
price of one trumohet =
price of clarinet = $159.95
