Answer:

$170$

Step-by-step explanation:

The angle 42x+1 is the inscribed angle of Arc WX. This means Arc WX is twice of 42x+1.

$wx = 2(42x + 1)$

We can add up that and the other arcs to 360.

$2(42x + 1) + 29x - 1 + 65x + 3$

$84x + 2 + 29x - 1 + 65x + 3 = 360$

$178x + 4 = 360$

$178x = 356$

$x = 2$

Plug in 2 for WX.

$84(2) + 2 = 170$

What is 3(2x+1)+2(x+3) Help please x

katrin [286]

Answer:

8x + 9

Step-by-step explanation:

Treat the question as 2 separate brackets

First expand 3(2x + 1) :

6x + 3

Then expand 2(x + 3) :

2x + 6

Now add the two answers together and simplify :

= 6x + 3 + 2x + 6

= 8x + 9

hope this helps :)

Answer:

$\pi$ radian

Step-by-step explanation:

We know that angle for a full circle is 2 $\pi$

In the given figure shape is semicircle

hence,

angle for semicircle will be half of angle of full circle

thus, angle for given figure = half of angle for a full circle = 1/2 * 2 $\pi$ = $\pi$

Thus, answer is $\pi$ radian

alternatively, we also know that angle for a straight line is 180 degrees

and 180 degrees is same as $\pi$ radian.
