A) The hypotenuse is the longest side of the triangle .In the figure EG is the hypotenuse.The given angle is <G=40 degrees.The side adjacent is FG= 10 units.
The question is asking us to find the trigonometry ratio which will help us find EG.We can use cos as cos is ratio of adjacent and hypotenuse.
B) Cos 40 =0.766.
Substituting tan40 value we have:
EG=13.05.
C)Sum of angles in triangle is 180.
<E+<F+<G=180
<E+90+40=180
<E+130=180
<E=50 degrees.
D) 
EF=8.39
E) Area of triangle EFG= 
A rea of the triangle = 
Area= 54.75 square units.
Answer:
=> ( 546 x 65 ) /35 = 294
total seats are there : 294 +546 = 840 seats
Step-by-step explanation:
Answer:
is the simplest form of given expression.
Step-by-step explanation:
The given question is 
To solve the problem we have to group or split middle term and then factorise
Taking 
common from first two terms of denominator and 2 from next two terms
Now,taking x common from first two terms of numerator and -1 from next two terms and in denominator taking(x-1) common from both terms
Now cancel out x-1 from both numerator and denominator we get
is the required simplest form.
