Pls solve for angle 2.

Mathematics

We know that with a straight line, the resulting angle is 180.
So, knowing this:
6x+12+5x+3=180
Solve for x
11x+15=180
11x=165
x=15
Plug x back into your respective angles
Angle 1: 6(15)+12=102 degrees
Angle 2: 5(15)+3=78 degrees
Therefore angle 2 is 78 degrees.

Step-by-step explanation:

The formula for the volume of a sphere is V = 4/3 πr³.

So

Given

Volume (v) = 57ft³

v =  \frac{4}{3} \pi {r}^{3}

57 =  \frac{4}{3}  \times 3.14 \times  {r}^{3}

57 = \frac{12.56}{3} \times    {r}^{3}

57 = 4.19 \times  {r}^{3}

{r}^{3}  =  \frac{57}{4.19}

{r}^{3}  = 13.6

r =  \sqrt[3]{13.6}

Therefore r = 2.4 ft

I gave my answers by rounding off. so if you don't round off then it's answer is 2.3 ft

How many digits are in the product of 91 and 10^17<br> please explain. Thanks.
LenKa [72]
It should be 19 because originally, it would be 910, but then add 16 more 0's, and 16 + 3 = 19 (and the three is from here -------^)!
Check this out ->:https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=91*10%5E17
and https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#safe=strict&q=91000000000...
They equal.

Find the slope of the graph of y=−45x−2.
andriy [413]

Answer:

The slope in this equation is 45.

Step-by-step explanation:

Slope-intercept form: y = mx + b

m = slope

b = y-intercept

x = variable

y = mx + b\\y = -45x -2

Someone, please help! Thank you!

Answer:

324°

Step-by-step explanation:

Totak angles in a 7 sided polygon = 900°

Side A = 3

Side B = 1

Side C = 4

Side D = 1

Side E = 5

Side F = 9

Side G = 2

Total = 25

The largest angle has the largest ratio which is side F

Angle in side F = Ratio of side F / total ratio × 900°

= 9/25 × 900°

= 0.36 × 900°

= 324°

The largest angle = 324°

The smallest angles are angles with the lowest ratio which are side B and side D

Angle in side B = Ratio of side F / total ratio × 900°

= 1/25 × 900°

= 0.04 × 900°

= 36°

The smallest angles are angles 36°
