8x + 26 = 98
8x = 72
x = 9
8x + 26 + z = 180
8(9) + 26 + z = 180
72 + 26 + z = 180
98 + z = 180
z = 82
Answer:
20,600, 6, 3.5, 5
Step-by-step explanation:
I GOT ANSWER AFTER GETTING IT WRONG
Cos( 6 x ) = 1/2
6 x = 60° ⇒ x 1 = 10°
6 x = 300° ⇒ x 2 = 50°
6 x = 420° ⇒ x 3 = 70°
6 x = 660° ⇒ x 4 = 110°
x 5 = 130°, x 6 = 170°, x 7 = 190° , x 8 = 230°, x 9 = 250°,
x 10 = 290°, x 11 = 310°, x 12 = 350°
