The answer is B because if the triangle is a polygon then the conclusion would be that it is either acute or obtuse.

Answer:

Step-by-step explanation:

You can rule out all others. A is wrong because a triangle cannot be acute and obtuse at the same time. C is wrong because a polygon dosen't neccassarily need to be a triangle, for example, a polygon is a closed shape, so it could be a rectangle. It isn't D because there are obtuse triangles out there. So, the only one left is B.

ABCD is a parallelogram. if side AB=5x+7 side BC=8x-12 and side CD=7x-14 find the value of x

SVETLANKA909090 [29]

The value of x=10.5 units

Step-by-step explanation:

Here you should have in mind that in a parallelogram, opposite sides are congruent. In this case, AB=DC

Given the expressions, AB= 5x+7 and CD=7x-14 then you can equate the two for the value of x

5x+7 = 7x-14

collect like terms

7+14=7x-5x

21=2x

21/2=2x/2

10.5 =x
