Answer:
The three questions about the given triangle has been answered below.
Step-by-step explanation:
We are given a right angled triangle whose sides are of length 20, 21 and 29.
<u>(1)</u> sin(B) = 
= 
= 0.72
<u>(2)</u> sin(A) = 
sin(A) = 0.689
∠CAB = 
∠CAB = 43.551°
<u>(3)</u> We suppose that cosA < sinA and we haveto find which all angles will satisfy this condition.For this the angle A should be greater than 45°.
From the given options the angles that satisfy this are 55 , 66 and 75.
45 is not included as then sinA = cosA and that condition is not there.
Answer:
The area of the clock 
Step-by-step explanation:
We have been given the face of the clock that is 
So that is also the circumference of the clock.
Since the clock is circular in shape.
So 
From here we will calculate the value of radius
of the clock that is circular in shape.
Then 
Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.
Now 
So the area of the face of the clock =
-18f - 34 - 14f = 11
-32f - 34 = 11
-32f = 45
f = -32/45
Simplify the fraction if needed!
Hope this helps, and please mark brainliest!
Answer:
the equation is x= 2908
Step-by-step explanation:
you need to find the number of books they had by taking the new total and subtract it by the number they add and that would equal x in the problem
