Please Help!! What is the measure of angle AXB?

Mathematics
2 answers:
Goshia [24]3 years ago

Answer:

Step-by-step explanation:

Two angles are supplementary when their sum is 180

∠AXB + ∠BXC = 180°   {Supplementary angles}

8x + 10 + 2x - 20 = 180    

Add the like terms

10x - 10 = 180

10x = 180 + 10

10x = 190

x = 190/10

x = 19°

∠AXB  = 8x + 10

          = 8 * 19 +10

          = 152 + 10

∠AXB  = 162

Answer:

180 degrees

Step-by-step explanation: the measure of angle AXB is ( a + a )  and the sum of the measured angles AXB and BXC  = 180 , so a + ( a + a) = 180.

both these angles add up to be 180 degrees because they are both supplementary angles  they both share the sides  of x  and b.  

if it confuses you, just use  a bit of repeated addition and multiplication

for example  : 30 + 30 + 30 + 30 + 30 = 5 x 30 which equals to 150

because you add 30 , 5 times .

The sum of the radius of the base and the height of a solid cylinder is 37m. If the total surface area of the cylinder is 1628 m
MA_775_DIABLO [31]

Answer:

4618.14m^{3} or 4618m^{3}  

Step-by-step explanation:

From  T.S.A = 2\pirh + 2\pir^{2}

 where T.S.A = 1628m^{2}

           1628 = 2\pirh + 2\pir^{2}

            1628 =  ( rh + r^{2} ) 2\pi

 by dividing both side by 2\pi

             \frac{1628}{2\pi }=  rh + r^{2}

          259.10 = rh + r^{2}

           rh = 259.10 - r^{2}

        h = \frac{259.10 - r^{2} }{r}   <u>          </u>(1)

From Radius + Height = 37

       r + h = 37  <u>              </u>(2)

by substituting eqn 1 into 2

    r + \frac{259.10 - r^{2} }{r}   = 37

by multiplying r to both side

   r^{2} + 259.10 - r^{2} = 37r

     259.10 = 37r

   r = \frac{259.10}{37}

   r = 7.00 ≅ 7  

From Eqn 2

     r + h = 37

     7 + h = 37

     h = 37 - 7

     h = 30

so Volume of a cylinder = \pi r^{2} h

                  V = \pi * 7^{2} * 30

                  V = 4618.14m^{3}  ≅  4618m^{3}

Natasha2012 [34]

Answer:

{( \frac{ {2x}^{4}  {y}^{4} }{ {4x}^{2} } )}^{3}   \\

open the bracket:

=  \frac{ {2x}^{(4 \times 3)}  {y}^{(4 \times 3)} }{ {4x}^{(2 \times 3)} }   \\

simplify:

=  \frac{ {2x}^{12}  {y}^{12} }{ {4x}^{6} }  \\

group x terms together:

= ( \frac{ {2x}^{12} }{ {4x}^{6} } ) \times  {y}^{12}  \\  \\  =  (\frac{ {x}^{(12 - 6)} }{2} ) \times  {y}^{12}  \\  \\  =  \frac{ {x}^{6} }{2}  \times  {y}^{12}

factorise out power 6:

{ \boxed{= \frac{ {(xy {}^{2}) }^{6} }{2}  }}\\
