The equilateral's lengths are all the same
Also if AB = AD = BD = CD that would mean all those sides have the exact same length
Answers and Explanations
15A. BCD has 2 acute angles and one obtuse angle, so this is an Obtuse Triangle
15B. If beforementioned = 5 cm
Then the perimeter is 5cm x 3 = 15cm
15C. ABC is a Right Triangle
16. abcdef. Measure the angles using a protractor
17. The shortest side of ABC is AB which is 5cm, the longest is AC which is 10cm
Shortest side: Longest side
5cm:10cm
1:2 is the ratio
Answer:
58%=0.58
Step-by-step explanation:
Step-by-step explanation:
a triangle,=180
so 68+35-180=77
then 77+68=145
Note that the measurements of the side of the squares are the same.
Area = base x height
Area = length x width
The area given is 400
Root 400 to get the length of the sides
√400 = 20
20 in. is your side measurement
hope this helps
