Answer:
1385.28 m²
Step-by-step explanation:
apothem = √16² - 8² = √256 - 64 = √192 = 13.86
Base area = 3 x 16 x 13.86 = 665.28
6 side area = 3 x 16 x 15 = 720
surface area = 665.28 + 720 =1385.28
Answer:
angle 11 they are vertically opposite.
Answer:
X=151
Step-by-step explanation:
1. 61+90= 151
-Combine the two given angles
2.180-151= 29
-Subtract the total of the two combined from 180 because all 3 angles of a triangle add up to 180.
-29 is your difference which is also the angle next to X.
3.180-29= 151
-To find angle X you subtract 29 from 180 because angle X and 29 are supplementary angles that add up to 180.
-Therefore X=151
The rate of mr Rodriguez to complete 1 job is 1/3 while
that of his assistant is 1/4.5.
So if mr Rodriguez works for 1 hour, the job left would be
2/3 of the job. So the total time needed by assistant is:
(2/3) / (1/4.5) = 3 hours
Answer:
<span>3 hours</span>
