Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for A
A = 180° - (90 + 48)° = 180° - 138° = 42°
----------------------------------------------------------
tan48° = 
= 
Multiply both sides by a
a × tan48° = 18 ( divide both sides by tan48° )
a = 
≈ 16.2 ( to the nearest tenth )
-----------------------------------------------------------
sin48° = 
= 
Multiply both sides by c
c × sin48° = 18 ( divide both sides by sin48° )
c = 
≈ 24.2 ( to the nearest tenth )
Answer:
$40
Step-by-step explanation:
Divide.
$800 / 20 hrs.
= $40
A^2+ b^2= c^2
24^2+b^2=25^2
576+b^2=625
Sub 576
b^2= 49 b=7
The answer is 160

<span>Answered by the following sums -
Outer square area = 4x^2
side of the square = 2x which is equal to diameter of circle == diameter of inner square.
radius of circle = x
diameter of outer square = 2*sqrt(2)*x
consider side of inner square = a
so a^2 + a^2 = (2x)^2
2a^2 = 4x^2
a = x*sqrt(2)
So area of inner square will be = 2x^2</span>
