Question

if sum of two smaller angles of a triangle is equal to the greatest angle then find the greatest angle​

Answer 1

Let the smaller angles be ‘x’ and ‘y’

Let the greatest angle be ‘z’

From the question,

x + y = z {equation 1}

According to Angle Sum Property,

x + y + z = 180

x + y + x + y = 180 {from equation 1}

2x + 2y = 180

2(x + y) = 180

x + y = 180/2

x + y = 90

z = 90 {from equation 1}

Therefore, the greatest angle is 90°

Answer 2

Answer:

greater side is 90 degree

Step-by-step explanation:

let the smaller angle =x

so as per the question

x+x+2x=180(angle sum property)

4x=180

x=180/4

x=45

larger angle=2x

=90
