as is ratio of 2 angle is 7:8
and third angle is sum of these two so
7x +8x+15x= 180
solve it and x =6 hence the answer
the sum of all the angles of a triangle i=180
let the given angles be 7x and 8x.
so that the third angle is 7x+8x=15x
7x+8x+15x=180(sum of all the angles of a triangle is 180)
the value of given angles
Therefore the third angle =42+48=90
this is because the sum of the angles is equal to the third angle ,it has been given
one angle of the
Let first angle =7x
Other angle = 8x
Third angle = 7x + 8x
Third angle=7x +8x=7×6+8×6=90
Please mark it as branliest
The other 2 angles are 4x and 5x for some value of x.
If the third angle is y then 4x + 5x + y = 180
And either y = 4x + 5x or 5x = 4x + y.
If y = 4x + 5x, then x = 10 and the angles are 40 and 50 and 90.
If 5x = 4x + y, then x = y and x = 18 and the angles are 18 and 72 and 90.
The ratio between other two angles of a triangle is 7:8
So lets suppose one of the other two angle is 7x°.
That means the second angle between those angles is 8x°.
But since the first angle is the sum of the other two angles.
=> First angle = 7x° + 8x° = 15x°.
We know that the sum of angles of a triangle is always 180°.
=> 15x° + 7x° + 8x° = 180°
=> x = 6°
●So first angle = 15×6 = 90°
●Second angle = 7×6 = 42°
●Third angle = 8×6 = 48°
●●●Hope it Helps●●●
Second angle =8x
Give that third angle equal to sim of the this two angles :.7x+8x=third angle
Then angles are
