Answer:
∠B =
Step-by-step explanation:
Given : a=7 b=10 and C is a right triangle
solution :
refer the attached figure .
Since ΔACB is right angled triangle so we will use trigonometric ratios .

Perpendicular = b =10
Base=a=7
Putting value in formula:




Thus ∠B =
The inverse of the given function is y = √5x + 7/2 - 3
<h3>Inverse of a function</h3>
Given the function expressed below;
5y + 4 = (x+3)² +1/2
5y = (x+3)² - 7/2
y = 1/5(x+3)² - 7/10
Replace y as x
x = 1/5(y+3)² - 7/10
Make y the subject of the formula
5x = (y+3)²- 7/2
(y+3)² = 5x + 7/2
y+3 = √5x + 7/2
y = √5x + 7/2 - 3
Hence the inverse of the given function is y = √5x + 7/2 - 3

The volume of oblique cone =
Now radius is doubled is now it is 2r
And height is reduced to 2/3 of its original size that is 2/3 h
So plugging the values we get volume
New Volume = 
= 

It means the volume becomes 4 times
20.50 * 0.8 = $16.40
16.40 * 0.4 = $6.56
Final selling price = $6.56
Answer:
Yes, there are infinite triangles with the same three angles but different side lengths
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent
therefore
There are infinite triangles with the same three angles but different side lengths
