Answer: Only the second image
Step-by-step explanation:
Draw a diagram as shown below.
The diagonals are equal in length. Because AB || DC and AD || BC, the quadrilateral is a square.
Because the diagonals bisect each other at O, therefore
DO = BO = 10.
Likewise,
AO = CO = 10
Because AB = 13, therefore DC = 13.
The perimeter of ΔCOD is CO + CD + DO = 10 + 13 + 10 = 33 in
Answer: 33 in
15 inches
the formula for the area of a triangle is Area=(1/2)(base)(height)
since the problem is looking for the height, we can rewrite it as
Height=(Area)/((1/2)(Base))
then the number must be substituted in
Height=(187.5)/((1/2)(25))
and the answer is 15 inches.
Answer:
To solve for the degree take the number that has the highest exponent. If they have equal exponents then see if you can simply further
