Step-by-step explanation:
The angles of triangle are 90°, 42° and 48°
Step-by-step explanation:
Given that one angle of a triangle is equal to the sum of other two. if the ratio of the other two angles is 7:8.
we have to find the angles of the
triangle.
Let the angles of triangle be x, y and z
As one angle of a triangle is equal to the sum of other two
x=y+z
also the ratio of the other two angles is
7:8.
y:z=7:8
Let y be 7a and z be 8a
:.x=7a+8a=15a
By angle sum property of triangle
x+y+z=180°
15a+7a+8a=180°
30a=180° → a=6
Hence, angles are
x=15a=15(6)=90°
y=7a=7(6)=42°
please mark it brainliest answer
z=7a=8(6)=48°
