Can someone please help me with this question.
Ber [7]

Answer:

square root of 2

Step-by-step explanation:

Sides are 1 and 1 and the hypotenuse is the longest side (opposite the right angle)

We can use pythagerouses theorem : a^2+b^2=c^2

this means that 1^2+1^2=c^2

1+1=c^2

2=c^2

c=2/sqrt

c is the square root of 2

the hypotenuse is the square root of 2

What is the answer to number 23
attashe74 [19]

The answer is 50/27 or 1 23/27 or approx 1.85185. Here is my work!

Multiply both sides by 10 : 20x + 6x = 50 - x

Collect the like terms: 20x + 6x = 50 - x

Move Variable to Left: 26x + x = 50

Collect like terms: 27x = 50

Divide both sides by 27: 50/27

Hope this helped :))
