Solution:
(tanx + tany)/(1-tanxtany) is equal to the formula of tan(x+y)
sinxcosy + cosxsiny = is equal to the formula of sin(x+y)formula
cosxcosy - sinxsiny) = is equal to the formula of cos(x+y)
So this means that
tan(x+y) = sin(x+y)/cos(x+y)
Answer:
Solution given:

now
f(x)+g(x)=
....(1)
now
factoring x²+6x-40
we get
x²+10x-4x-40
x(x+10)-4(x+10)
(x+10)(x-4)
now substituting in equation 1 ,we get
f(x)+g(x)=
taking l.c.m
=
=now
opening bracket

=
So
answer is :
B. 
KF= 8 units
m∠DEK = 88°
m∠DFE = 90°
Answer:

Step-by-step explanation:
Given: Figure
To find: distance from the right center field fence to third base
Solution:
In a right angled triangle,
using Pythagoras theorem, square of hypotenuse is equal to sum of squares of base and perpendicular.
In ΔBAC,

So,
distance from the right center field fence to third base is 381.5 foot.
Answer:
x=4
Step-by-step explanation:
x-8= x/2 -x-6/3
x-8=x/2-x-2
x-8=-x/2-2
1.5x-8=-2
1.5x=6
x=4
