A quadrilateral has exactly one right angle and two nonadjacent angles that each measure 105 degrees
LiRa [457]

Answer:

C) Kite

Step-by-step explanation:

The problem states that the polygon is a quadrilateral, meaning it has 4 sides. This rules out D, as pentagons have 5 sides. Our next clue is that this shape has <em>only one </em>right angle, ruling out A and B, because, by definition, rectangles and squares must have four 90 degree angles. We can already see that we are left with only one choice, but to confirm: a kite has 2 opposite angles of 105 degrees, like the problem states.

Therefore, the answer is C) Kite

Hope this helps!

Answer:

  • 40 sq. units

Step-by-step explanation:

<h3>Solution 1</h3>

The figure (kite) is symmetric and covers half of the area of rectangle with sides 8 units aby 10 units

<u>The area of the rectangle:</u>

  • A = 8*10 = 80 sq. units

<u>The area of the kite:</u>

  • A = 1/2*80 = 40 sq. units
<h3>Solution 2</h3>

Split the kite into two triangles and calculate their area and add up

<u>Triangle DCB has b = 8, h = 2 and has area:</u>

  • A = 1/2*8*2 = 8 sq. units

<u>Triangle DAB has b = 8, h = 8 and has area:</u>

  • A = 1/2*8*8 = 32 sq. units

<u>Total area:</u>

  • 8 + 32 = 40 sq. units

Neko [114]

Answer:

3

Step-by-step explanation:

  • <em>Each of the seven happy clowns has a red nose.</em>

This means there are (15-7) 8 sad clowns.

  • <em>Five of the sad clowns have red noses. </em>

This means out of 8 sad clowns, 5 have red noses. So the clowns that have to act sad and have red noses are (8-5) 3.
