AO=CO
two congruent radii

Triangle ABO is a right-angled triangle

AO=32
BO=BC+CO=98+32=130
AB=\sqrt{(121^2-32^2)}= \sqrt{15876} =126

That is it!

Done :)

Use Pythagoras to calculate AB:

CO = AO  = 32    (Are rays.)
BO = BC + CO = 98 + 32 = 130
AB ⊥ BO
⇒  ΔAOB   is a rectangular triangle.
We use Pitagora's theorem.


\displaystyle\\
AB =  \sqrt{BO^2 - AO^2}  = \sqrt{130^2 -32^2}=\\\\
= \sqrt{16900 -1024}= \sqrt{15876}= \boxed{126 }

Solve and simplify<br> 3. (y^2-7y-5)-(-3y^2+3y-4)
yKpoI14uk [10]

(y^2-7y-5)-(-3y^2+3y-4)=y^2-7y-5-(-3y^2)-3y-(-4)\\\\=y^2-7y-5+3y^2-3y+4

<em>combine like terms</em>

=(y^2+3y^2)+(-7y-3y)+(-5+4)=\boxed{4y^2-10y-1}

A mystery number is multiplied by 11 then 10 is subtracted from it to give you a result of 34. What is the mystery number?
klemol [59]

Answer:

4

Step-by-step explanation:

And let the missing number be x

We can solve using Algebra

11x - 10 = 34

11x = 34 + 10

11x = 44

x = 44/11

x = 4

For verification:

4(11) - 10 = 34

44 - 10 = 34

34 = 34

Hence, Proved
