Answer:
AnSum of two sides of triangle always greater than third side, so the possible values of h is:
7x-3x < h < 7x+3x
4x < h < 10x answer:
Step-by-step explanation:
Answer:
X=
Y=
Step-by-step explanation:
The first one is 45-45-90 right angled isosceles triangle.
The length of the hypotenuse ie.X can be found with the help of Pythagoras Theorem.

where a and b are the remaining sides of the triangle,

X=
In the second triangle we have to apply trigonometry,
cos θ=
cos 30°=
=
Thus, Y=
inches
