Answer:
D. 1800°
Step-by-step explanation:
The given polygon has 12 sides.
The formula for finding the sum of the interior angles of an n-sided polygon is given as, ( n − 2 ) × 180.
Where n is the number of sides of the polygon.
Thus, the sum of the interior angles of the 12 sided polygon given above is:
(12 - 2) × 180
= 10 × 180 = 1800°
<em>Sum of the measures of the interior angles of the 12-sided polygon is D. 1800°</em>
Answer:
Step-by-step explanation:
6x + 5x + 26.5 + 7x - 8 + 4x+21.5+5x+19+10x+13.5 = 720
37x + 72.5 = 720
37x = 647.5
x = 17.5
Vertices = 105 deg, 114 deg, 114.5 deg, 91.5 deg, 106.5 deg, 188.5 deg
Answer:
D. No, there isn’t enough information because only two pairs of corresponding sides can't be used to prove that two triangles are congruent.
Step-by-step explanation:
Time for equipment elevator = 11 seconds + 27 seconds = 38
Time for elevator for miners = 27 seconds
Speed of equipment Elevator = 7 feet/ sec
Speed of Miner elevator = 16 feet/ sec
Distance traveled by Equipment Elevator = Speed * time
= 7 * 38 = 266
Distance traveled by Miner Elevator = Speed * time
= 16 * 11 = 176
266 > 176
Therefore, The Equipment Elevator is deeper than the Miner Elevator
Depth of Equipment Elevator = 266m
Depth of Miner Elevator = 176m
