Question

4
In ∆ A B C, the measure of angle A is equal to
the sum of the measures of LB & LC. Also
the ratio of measures of LB & Lc is 4.5
Then find the measure of angles of the triangle​

Answer 1

Answer:

in triangle abc the measure of angle A is equal to the sum of measure of Angle B and angle C also the ratio of measures of Angle B and angle C is 4 is to 5 then find the measures of angle of triangle

Answer:Angle A= B + Cangle B:angle C = 4x : 5xangle A = 4x

Answer 2

ǟռֆաɛʀ :

Angle A= B + C

angle B:angle C = 4x : 5x

angle A = 4x + 5x =9x

angle A + B+ C = 180

9x+9x=180

18x=180

X= 10

angle A = 90

B= 40

C= 50
