Find the value of x.

#9,10,11,&12

Step-by-step explanation:

9). It's given in the triangle → Two angles are equal in measure

   Therefore, by the definition of an isosceles triangle, opposite sides of the equal angles are equal in measure.

   x = 12

10). Two sides of the given triangles are equal in length.

    By the definition of an isosceles triangle, opposite angles of the equal sides of the triangle will be equal in measure.

    Therefore, y = 55°

    By the triangle sum theorem,

    x° + y° + 55° = 180°

    x° + 55° + 55° = 180°

    x = 180 - 110

    x = 70°

11). By the definition of an isosceles triangle, opposite sides of the equal angles will be equal in measure.

    x + 3 = 12

    x = 9

12). By the definition of an isosceles triangle, opposite angles of the equal sides of the triangle will be equal in measure.

    m∠2 = 53°

    x + 65 = 53

    x = 53 - 65

    x = -12

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
