Answer:
5. DBE and CBA both=48 degrees
6. a. scalene, right
b.isosceles, obtuse
c. scalene, acute
7. 50 degrees
8. im not completely sure how to do this one but ill check into it
Step-by-step explanation:
its a lot to explain, in 5 find p and plug it in.
in 6, just look at the sides and angles.
scalene- no sides equal
isosceles- 2 sides equal
equilateral- all sides equal
right- one 90 degree angle
acute- all acute angles (less than 90)
obtuse- one obtuse angle (more than 90)
7. add 90 and 40 to get 130. 180-130=50
8. im gonna look up how to do this one right now
I'd he happy to, But you forgot to post the question.
Answer:
52 in approx
Step-by-step explanation:
Given data
Length of TV= 42 in
Widht of TV= 31 in
Required
The diagonal of the TV
Applying the Pythagoras theorem
D^2= L^2+W^2
D= √L^2+W^2
D= √42^2+31^2
D=√1764+961
D=√2725
D=52.20 in
Hence the diagonal of the Tv is 52 in approx
