Answer:

42, 138, 138

Step-by-step explanation:

the line not adjacent to the 42 degree angle is also 42 by the vertical angles theorem. Then you find the measure of the other 2 by x+42=180 so x=138.

42,138,138 correct
The line not adjacent to the 42 degree angle is also 42 by the vertical angles theorem then you find the measure of the other 2 by x+42=180 so x=138 this is correct but there’s more ways to do too ...

if you have a rectangle with a length of 0.5 x + 10 feet and a width of 6 feet how could you find the area written in its simple
Greeley [361]
<h2>Greetings!</h2>

Answer:

x + 20 = area

Step-by-step explanation:

You need to recall the equation for a rectangle:

Width x Length = Area

So simply plug the values into this:

(0.5x+10) * 6

(0.5x * 6) + (10 * 6)

= 3x + 60

Simplified down by dividing by three:

\frac{3x}{3} + \frac{60}{3} = area

<h3>x + 20 = area</h3>

2. Evaluate the geometric series given a = -120, r = 0.5 and n = 6
Tju [1.3M]

Here we're discussing the "nth partial sum of a geom series."

                                                       1 - r^n

The formula for that is s(n) = a(1) --------------- 

                                                         1-r

We can subst. the given values and see where that takes us:

                  1 - (-2)^6        1 - 64

105 = a(1)*---------------- = ----------*a(1)  =  -21*a(1)

                    1-(-2)                3

                                              105

Solving this for a(1):  a(1) = --------- = -5    (answer)

                                              -21
