Answer:
6in...8in...and...10in
Two sides must use the pythagoras theorem to obtain the hypothenus
square root of 8 squared plus 6 squared so as to obtain a 10...hence making it a right angled triangle
If it was 25%, it would be a 90 degree angle. So we can calculate this using a proportion. 25/90 = 24/x. Cross multiply to get 25x = 2160. When you divide by 25 on both sides you get 86.4. So the angle should be 86 degrees. Hope this helps.
The value of –3mn + 4 = –3 when m = 2 and n = 4 is –20
Solution:
Given expression is –3mn + 4 = –3.
To find the value of –3mn + 4 = –3 when m = 2 and n = 4.
⇒ –3mn + 4 = –3
Add 3 on both sides of the equation.
⇒ –3mn + 4 + 3 = –3 + 3
⇒ –3mn + 7 = 0
Substitute m = 2 and n = 4
⇒ –3 × 2 × 4 + 7
Using BODMAS rule first do the multiplication.
⇒ –6 × 4 + 4
⇒ –24 + 4
⇒ –20
Hence the value of –3mn + 4 = –3 when m = 2 and n = 4 is –20.
For this case we have that by definition, the equation of a line of the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have to, if two lines are parallel then their slopes are equal.
If we have 
with slope 
, then a parallel line will have slope 
Thus, the equation of the parallel line is of the form:
We substitute the given point and find "b":
Finally, the equation is:
