Question

the given figure the measure of
( a + b +c + d + e + f+ g+ h+ i +j) =??

Answer 1

Angle O = 360° * whole angle  There are 5 triangles in this figure. And sum of angles of each triangle measure 180°. So sum of 5 such such triangles is 900°. And subtracting angle O from 900, we get 540°. Hence ( a + b + c + d + e + f + g + h + i + j) = 540 °

Answer 2

Answer:

540 degree

Step-by-step explanation:

Dear student

In the given figure The angle where all the triangles meet are making an angle of 360°.And also we know that by angle sum property of triangle, the sum of all the angles of a triangle measures 180°So, According to figure,a+b+c+d+e+f+g+h+i+j+360°=180°×5     [∵there are 5 triangles]⇒a+b+c+d+e+f+g+h+i+j=900°−360°⇒a+b+c+d+e+f+g+h+i+j=540°In the given figure The angle where all the triangles meet are making an angle of 360°.And also we know that by angle sum property of triangle, the sum of all the angles of a triangle measures 180°So, According to figure,a+b+c+d+e+f+g+h+i+j+360°=180°×5     ∵there are 5 triangles⇒a+b+c+d+e+f+g+h+i+j=900°-360°⇒a+b+c+d+e+f+g+h+i+j=540°
