Question

Find the angles of a triangle, if its angle are (5x) , ( 2x + 10 ) and ( 3x - 10) degree.

Answer 1

Answer:

90°,46° and 44°

Step-by-step explanation:

Generally the sum of the all angles in a triangle is 180°

So. ===>>> (5x)°+(2x+10)°+(3x-10)°=180°

===>>> 5x+2x+3x=180

===>>>. 10x=180

===>>>. X=180/40=18°

The angles are 90 46,44 of the triangle

Answer 2

5x+2x+10+3x-10=180 degree

10x+0=180 degree

10x=180 degree

x=180/10

x=18

∴ 5x=5x18=90 degree

∴ 2x+10=2x18+10= 36+10=46 degree

∴ 3x-10=3x18-10=54-10=44 degree

∴ 5x=90 degree

∴2x+10=46 degree

∴3x-10=44 degree
