Solve this sum.... maths |

Answer» here is your answer mate: since AB = AC it is an isosceles triangle with ANGLE B = angle C thus, angle A = 2x angle B = angle C = x + 10 according to the angle sum property of the triangle, angle A + angle B + angle C = 180 angle A + 2 angle B = 180 2x + 2(x + 10) = 180 2x + 2x + 20 = 180 2(x + x + 10) = 180 x + x + 10 = 90 2x + 10 = 90 2x = 80 x = 40 therefore, angle A = 2x = 80 degrees angle B = angle C = x + 10 = 50 degrees hope this answer helps you buddy please mark as BRAINLIEST:-) |

In a triangle ABC AB:BC=3:4 BC :AC =5:4A) If AB=30 degre .what is the length of BCB ) what is AB:BC:AC |
|
Answer» Answer: (A) The LENGTH of BC 40°(B) AB : BC : CA = 15 : 20 : 16Step-by-step explanation: Given as : For any TRIANGLE ABC The RATIO are as AB : BC = 3 : 4 BC : AC = 5 : 4 Or, So, And So , Therefor the ratio can be written as AB : BC : CA = 15 : 20 : 16 Let The length of AB = 15 x The length of BC = 20 x The length of CA = 16 x A/Q AB = 30° Or, 15 x = 30° ∴ x = i.e x = 2° Put the value of x in BC value i.e The length of BC = 20 × 2° = 40° Hence, (A) The length of BC 40° And (B) AB : BC : CA = 15 : 20 : 16 Answer |
