Question

Q24.
In triangle ABC, if angleA= (2x-5), angleB= (5x+ 5) and angleC= (3x+ 50), then find the values of x and angleC.​

Answer 1

Answer:

X = 13 & C = 89.

Step-by-step explanation:

As per the angle sum property of a triangle,

A + B + C = 180

=> 2x-5+5x+5+3x+50=180

=> 10x+50=180

=> x+5=18

=> x=13.

Angle C = 3×13+50 = 39+50 = 89.

So, the answer is X = 13 & C = 89.

Answer 2

Answer:

X=13, C=89°

Step-by-step explanation:

we know that sum of angles in a triangle is equal to 180°

2x-5+5x+5+3x+50=180

10x+50=180

x=13

substitute x value in angle C

C=(3×13)+50

C=89°
