A triangle has base 10 cm long and the base angles of `50^(@) and 70^(@)`. If the perimeter of the triangle is `x+y cos z^(@)` where `z in (0, 90)` then the value of `x+y+z` equals :

A triangle has base 10cm long and the base angles are 50^(@) and 70^(@) .If the perimeter of the triangle is x+y cos(z^(@)) where z in(0,90^(@)) ,then find the value of (x+y+z) .

the degree measure of three angles if a triangle are x,y and z If z=(x+y)/2 then find the value of z

The sides of a triangle are x,y and z .if x+y=7,y+z=9 and z+x=8. then find the area of the triangle.

A point 'P' is an arbitrary interior point of an equilateral triangle of side 4. If x, y, z are the distances of 'P' from sides of the triangle then the value of (x+y+z)^(2) is equal to -

The length of the base of an isosceles triangle is 2x - 2y + 4z , and its perimeter is 4x + 6z . Then the length of each of the equal sides is

Area of the triangle formed by (x,y+z),(y,z+x),(z,x+y) is

In a triangle PQR mark the points X, Y, Z in the interior of triangle PQR
