Question

1 In the given figure find x
​

Answer 1

Answer:

Here, The value of x is 28° and all the angles of this triangle are of 80°,96° and 4°.

Step-by-step explanation:

Here, As per our given question,

=5x-60°+2x+40°+3x-80°=180° (By Angle sum property of a triangle)

=10x-100°=180°

=10x=180°+100°

=x=280°/10

=x=28°

So, Angles are,= 5×(28°) -60°=140°-60°=80°

=2×28°+40°=56°+40°=96°

=3×28°-80°=84°-80°=4°

So, Angles of this triangle are of 80°, 96° and 4°.

Thank you.

Answer 2

Answer:

We know that the sum of interior angle of triangle is 180

So

5x - 60 + 2x + 40 + 3x -80 = 180

As we simplify

10x - 100 = 180

10x = 280

x = 280/10

x = 28
