Why the following triangles are congruent!

Mathematics
1 answer:
dimaraw [331]2 years ago
7 0

Answer:

Because the sides BO and MA are marked with one line through the middle, which means those sides are congruent, angle A and Angle O are marked with one line, the angles are congruent, and angles W and N are marked with two lines, which means they are congruent. Therefore the triangles are congruent

A cylinder with a radius of 1 cm and a height of 21 cm has the same volume as a cone with a height of 7 cm. What is the radius o
Maru [420]
Volume of the cylinder = πr²h = π(1)² (21) = 21π cm³

Volume of the cone = 1/3 π r² h

21π = 1/3 π (r)² (7)

r³ = 21π ÷ (7/3 π) 

r² = 9

r = 3

Answer : Radius = 3

Factor completely<br> 6n2 – 11n – 10
Pepsi [2]

Step-1 : Multiply the coefficient of the first term by the constant   6 • -10 = -60

Step-2 : Find two factors of  -60  whose sum equals the coefficient of the middle term, which is   -11 .

     -60    +    1    =    -59

     -30    +    2    =    -28

     -20    +    3    =    -17

     -15    +    4    =    -11    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -15  and  4

                    6n2 - 15n + 4n - 10

Step-4 : Add up the first 2 terms, pulling out like factors :

                   3n • (2n-5)

             Add up the last 2 terms, pulling out common factors :

                   2 • (2n-5)

Step-5 : Add up the four terms of step 4 :

                   (3n+2)  •  (2n-5)

            Which is the desired factorization

Final result :

 (2n - 5) • (3n + 2)

How to rationalize the denominator of sqrt(a)/sqrt(a)-2
aivan3 [116]

Answer:

√a(√a + 2)          a - 2√a

----------------- = -----------------

    a - 4                a - 4

Step-by-step explanation:

I am assuming that by "sqrt(a)/sqrt(a)-2" you meant:

√a

----------

√a - 2

To rationalize the denom., multiply numerator and denom. of this fraction by the conjugate of √a - 2, which is √a + 2:

√a(√a + 2)

-----------------

    a - 4
