Answer:
Step-by-step explanation:
In any triangle the sum of all internal angles is 180.
You know that it is a right triangle son one anlge is 90° and they give you another angle wich is 42.3
So the solution for your missing angle is 180-90 - 42.3 = 47.7°
Answer:
if the whole (100%) is 50 homes, then half of the whole (50%) is 25 homes. the part of the whole, the homes cleaned, is 15 homes (30%)
so:
50 homes: 100%
25 homes: 50%
15 homes: 30%
Answer:
You can use Pythagorean Theroum, its not that hard. Use the formule a^2+b^2=c^2
The a is one side, the b is also another side but the C is the hypot use. The hypotunes (the largest side of a triangle) is usually the diagonal of the triangle like the one thats the longest.
(I’m gonna do a few)
1) 10^2+7^2=c^2
100+49=c^2
149=c^2
square root of 149 is about 12.21
(Skipped to 3 because of different example)
3) We know the hypotenuse but we don’t know B
so
16^2+b^2=27^2
256+b^2=729
b^2=473
About 21.75
6) Well this is a trapezoid and we want to find the side
So the two triangle’s sides are 17 and 19
We know 17 and 19 becuase the 17 was stated and the 19 was equal on both sides
use pythagoream theorem
17^2+b^2=19^2
289+b^2=361
B^2=72
8.49
Now thats the triangle’s sides
Now we double it becuase there are 2 of them
8.49(2)=16.98
Now we subtract that from 31
31-16.98=14.02
x=14.02
(I’d do more but I have no more space)
Answer:
Step-by-step explanation:
The formula for the volume of a cone is
the diameter is 6
radius = diameter/2
so radius is 3
and height is 12
plug it in and you would get 113.1
