Answer:
389.89879489
Step-by-step explanation:
1. Multiply
(5.68^3 × 8.14= 1491.65851648)
94100 × √38.2 / 1491.65851648
<u>2</u><u>.</u><u> </u><u> </u><u>evaluate root</u>
(√38.2 = 6.18061485)
94100 × 6.18061485 / 1491.65851648
<u>3</u><u>.</u><u> </u><u> </u><u>multiply </u>
(94100 × 6.18061485 = 581595.85796324)
581595.85796324 / 1491.65851648
<u>4</u><u>.</u><u> </u><u> </u><u>divide</u>
(581595.85796324 / 1491.65851648 = 389.89879489)
135.05 = 50 + 9.45x
85.05 = 9.45x
x = 85.05/9.45
x = 9

Step-by-step explanation:
Answer:
∠5 = 60°
∠6 = 30°
∠7 = 120°
Step-by-step explanation:
Since the polygon is regular, you know that the central angle (7) is 1/3 of the circle, or 120°. The angle 5 is half that measure, so is 60°, and the angle 6 is the complement of angle 5, so is 30°. (Angle 6 is also half the inscribed angle at each vertex, said inscribed angle being 120°/2 = 60°.)
∠5 = 60°
∠6 = 30°
∠7 = 120°
