Flauer [41]
The given angles are complementary, therefore:

(5r + 5) + (8r -6) = 90°

13r - 1 = 90
13r - 1 + 1 = 90 + 1
13r = 91

13r/13 = 91/13

The given sequence;–3.2, 4.8, –7.2, 10.8, is a geometric progression common ratio of -1.5.

<h3>What is a geometric series?</h3>

When all the terms of a geometric sequence are added, then that expression is called geometric series.

The given sequence ;

–3.2, 4.8, –7.2, 10.8, …

in parallelogram abcd angle b is a right angle determine whether the parallelogram is a rectangle if so by what property​
Digiron [165]

Answer:

If a parallelogram has at least one 90 degree angle then its opposite angle is equal and also = 90 degrees.  

The 2 remaining opposite angles add up to 180 degrees and since they must be equal, they must be 90 degrees each.

So, we have a quadrilateral with four 90 degree angles and is therefore a rectangle OR it could possibly be a square.
