Answer:
EH = 3.31
Step-by-step explanation:
We have been given a right angle triangle EKL. As KH has been given as the altitude (perpendicular) of the right angled triangle, and K is the right angle, we can say that EK is tthe base of the triangle and EH is the only side lleft, which is the hypotenuse of the triangle.
Where,
EK = Base = 3
KH = perpendicular altitude
EH = Hypotenuse
m<K = 90
m<E = 25
We know that
cosθ = Base/ Hypotenuse
cos 25 = 3/ EH
EH = 3/cos25
EH = 3.31
Perpendicular alitutude can also be calculated by using the formula for tanθ.
Answer:
3
⋅
x
x
+
y
Explanation:
The product of 3 and x divided by the sum of x and y is
P
r
o
d
u
c
t
o
f
3
and
x
S
u
m
o
f
x
and
y
.
Okay break it into smaller parts. The product of
3
and
x
is
3
⋅
x
um of
x
and
y
is
x
+
y
Now, we get
3
⋅
x
x
+
y
and that's it
3(y+10) = 3(3). For additional simplification, the answer may be written as
y+10 = 3
