Question

If the two opposite angles of a parallelogram are (3x+5)° and (4x-10). Find all the angle
of the parallelogram. pls don't write nonsense​

Answer 1

Step-by-step explanation:

We know that opposite angles of parallelogram are equal

so, 3x+5 = 4x-10

3x-4x = -10-5

-1x = -15

x= 15

therefore the angles are

3(15)+5= 50°

and 4(15)-10= 50°

sum of angles of quad. is 360°

so let the other to angles be a and b

therefore 50° + a + 50° + b = 360°

100°+ a + b = 360°

a+ b = 260°

we know that a = b

therefore 2a = 260

a = 130

so the angles are 50°, 130° , 50° , 130°

Here's your answer
