Answer:
A) False - not a right angle
B) True - it is a right angle
C) True - it is a right angle
D) False-not a right angle
Step-by-step explanation:
A) a*a+b*b=c*c (Asquared+Bsquared=C squared)
2*2+ 3*3 = 4*4
4+9=16
13 does not equal 16
B) 5*5+12*12=13+13
25+144=169
169=169 - True
C) 3*3+4*4=5*5
9+16=25
25=25 (True)
D) 4+ Root of 3 = Root of 19
False - square root of a prime number is irrational
IF X+Y=15. AND y=2x-3.
X + 2X - 3 = 15.
6 + 2 (6) - 3 =15
6 + 12 -3 = 15
18 -3 = 15
Solve for X.
WOO!
X=6 :D
Now try to see if anything else can be X.

Answer: 617 ft.
Step-by-step explanation: So first, the formula is A=C²/
4π, knowing this, let's just plug in our numbers
A = C² / 4 · π
A = 88² / 4 · 3.14
A = 7744 / 4 · 3.14
A = 7744 / 12.56
A = 7744 / 12.56
A = 616.56
A ≈ 617
Hope this helps :)
