The length of the sides of the board are 12. (12 times 12 equals 144).
The answer is b because all you have to do is just subtract if I am wrong so sorry
Answer:
x= -2
Step-by-step explanation:
First since 2 of the options ask for the width of BM lets solve for it using the Pythagorean theorem for both sides of point L:
a² + b² = c²
30² + b² = 50²
b² = 50² - 30²
b² = 1600
b = 40 Line BL = 40 ft
Since the ladder is 50 feet it is the same length on the other side as well
a² + b² = c²
40² + b² = 50²
b² = 50² - 40²
b² = 900
b = 30 line LM is 30 ft
SO line lm + line bl = 30 + 40 = 70 ft
A is true because ^
B isn't true because as we solved for earlier, BL is 40
C is true because line LM is in fact 30 ft as we solved for
D is not true because as we said earlier BM is 70
E is true because the same ladder was used on both sides of the street
3+a/2-6b in a couple weeks ago I have a couple things to say I don’t have a problem I just saw you I don’t know how to say hi I don’t have any money for that I just don’t know how to get a hold of me because I’m going out of the house to do a job I have a couple things to go and then I’m gonna be there for you and then you have a couple things that you want me to go out with your dad if not I’m done I just don’t do that you know that I’m going out of my money to do it I just want you know what
