A triangle has side lengths of 21, 27, and 35 inches. Is it<br> right triangle?
DIA [1.3K]
Answer: No
In right triangle we have 30:60:90
and the ratios are
x: x root of 3: 2x
so, for example, if we have side of length 3 against 30 degrees, then against 60 degrees the side will be 3 root of 3, and against 90 degrees it will be 6.
Hope it helps!

Pete has an old playstation that he bought for $400.
katrin2010 [14]

Answer:

1 year= $280

Step-by-step explanation:

30% of 400= 0.3 * 400= 120

400-120= 280

after one year the playstation cost 280

30% of 280= 0.3 * 280= 84

280-84= 196

after 2 years it cost $196

multiply the number by 0.3 to get 30% of the total

In isosceles pqr with base , pq = 2x + 3, and pr = 9x - 11. what is the value of x?
Anon25 [30]
First, draw and label a rough sketch of an isosceles triangle. Now put in the values of pq=2x+3 and pr=9x-11 

You know that the triangle is isosceles, therefore, the sides pq and pr are identical.  

Now, make the equations equal to each other to find the value of x. 

2x+3=9x-11 
3+11=9x-2x 
14=7x 
14/7=x 
2=x 

Therefore the value of x=2. 

Hope I helped :)
