Is DEF a right triangle? True or false
umka2103 [35]
Short answer = false
Remark

If it is a right triangle, it will obey the Pythagorean Equation. a^2 + b^2 = c^2. Let's see if it does.

Equation
a^2 + b^2= c^2
c must be the longest line. (Hypotenuse)

Givens
a = 24
b = 17
c = 40

Sub and Solve
a^2 + b^2 = c^2
17^2 + 24^2 = c^2 [We'll see if this comes out to 40]

289 + 576 = c^2
865 = c^2 which is no where near what 40^2 equals. 40^2 = 1600

Short answer False

Square root of 865 = (865)^1/2 = 29.4

What is the value of y?<br><br> A. <br> 16<br><br> B. <br> 48<br><br> C. <br> 64<br><br> D.<br> 132
lorasvet [3.4K]

Answer:

3x+3x+7x+20+7x+20=360

20x=360-20

20x=320

x=16

therefore x=16 so,

7x+20+y=180

but x=16

7(16)+20+y=180

y=180-132

y=48

Rama09 [41]

Hello,


if y≠0 then


ay^2-[-5y-y(-7y-9)]-[-y(15y+4)]=0\\\\ay^2-[-5y+7y^2+9y]-[-15y^2-4y]=0\\\\ay^2+5y-7y^2-9y+15y^2+4y=0\\\\ay^2+8y^2=0\\\\(a+8)y^2=0\\\\a=-8\\\\\\
