Answer:

57°

Step-by-step explanation:

Exterior Angle Theorem: An exterior angle of a triangle is equal to the sum of the opposite interior angles.

(9x+16) + (6x+15) = 136

15x + 31 = 136

15x = 105

x = 7

plug into (6x + 15)

6(7) + 15 = 42 + 15 = 57

The sun produces 3.9 ⋅ 10 to the 33th power ergs of radiant energy per second. How many ergs of radiant energy does the sun prod
arlik [135]
So the sun produces 3.9x10³³/ second

Using this ratio (3.9x10³³/ second) we can use the porpotions to calculate time taken (T) to produce 1.55x10⁷.

\frac{3.9(10^3) ergs}{1 second} =  \frac{1.55(10^7)ergs}{T}

Then isolate T and find the time

\frac{T3.9(10^3)ergs}{1 second} = {1.55(10^7)ergs
T3.9(10^3)ergs = ({1.55(10^7)ergs)seconds
T =  \frac{(1.55(10^7)ergs)seconds}{3.9(10^3)ergs}
T =  \frac{(1.55(10^7)seconds}{3.9(10^3)}
T = \frac{1.55}{3.9}(10^4)seconds
T = 0.397(10^4)seconds
T = 3.97(10^-^1)(10^4)seconds
T = 3.97(10^3)seconds

Thus it took 3.97x10³ seconds for 1.55x10⁷. of ergs to be produced
Hope that helped and if it did, a Brainliest rating would be much appreciated

A bag contains white marbles and green marbles, 62 in total. The number of white marbles is 3 less than 4 times the number of gr
Sedaia [141]

Answer:

There are 49 white marbles.

Step-by-step explanation:

w + g = 62        (w = white and g = green marbles).

w = 4g - 3

w - 4g = -3        Subtract this equation from the first equation:

g - (-4g) =  62 - (-3)

5g = 65

g = 65/5 = 13.

So w = 62 - 13 = 49.
