On major arc it will be 30° i.e. 1/2 of 60°

Satyam Kumar 4 years, 11 months ago

angle at the centre in triangle with side r,r and chord=r =60° =>reflex angle at centre is equal to 300°that is angle subtended bu major arc at centre this implies the chord or you can say major arc will subtend an angle =150°in the minor arc. Reason: {since the angle subtended by an arc at the centre is double the angle subtended by it on the remaining part of the circle}

AB=BC when two sides of any triangle so the triangle is isosceles triangle. isosceles triangle has two sides and two angles are equal angle C = angle A So angle A + angle B + angle C=180° 2angle A= 180° - 60° angle A=120°/2 angle A =60°

Given : Equations of the line 3x + 2y - 6 = 0 and x + 2y - 6 = 0

To Find : Area of the triangle formed by 2 lines and x-axis.

Solution:

Equation of the first line is 3x + 2y - 6 = 0

Slope-intercept form of the equation is,

2y = -3x + 6

---------(1)

Table for input-output values will be,

x 0 2 4

y 3 0 -3

Similarly, second equation is,

x + 2y - 6 = 0

2y = -x + 3

y = --------(2)

Table for input-output values will be,

x 0 2 6

y 3 2 0

Now by plotting these points we get a triangle with vertices (0, 3), (2, 0) and (6, 0)

Area of the given triangle =

Base = 4 units

Height = 3 units

Area = = 6 square units

Shazia Sk 4 years, 11 months ago

3x+5x+9x+13x=360° 30x=360° x=360÷30= 12 Now, to find the angles, let's put the value of x 3x= 3×12= 36 5x= 5×12= 60 9x= 9×12= 108 13x= 13×12= 156 Hence, the 4 required angles of the quadrilateral are: 36, 60, 108 and 156 Hope this helps you.
