Im so confused! Can someone help me? I need to find the value of the variable and the measures of the angles.....

nikdorinn [45]

Hello there! I can help you! So what we are looking for is the value of x. To find the value of x, we can write and solve an equation. Set it up like this:

4x + 28 = 180

This is because the sum of the angles for a triangle is 180°. We combine the like terms to get 4x and subtract 6 from 34 to get 28. First off, let's subtract 28 from both sides. 28 - 28 cancel out. 180 - 28 is 152. That simplifies into 4x = 152. Now, divide each side by 4 to isolate the x. 4x/4 cancels out. 152/4 is 38. There's a possible value of x. Let's plug the value in and see if it works. 38 * 2 is 76. 76 - 6 is 70. 38 + 34 is 72. 70 + 72 is 142 and 142 + 38 is 180. 180 = 180. There. x = 38. Here are the answers for the angle measurements:

(x + 34) = 72°
(2x - 6) = 70°
x° = 38°

Calculate s5 for the sequence defined by

pantera1 [17]

ANSWER

$S_5= 42.5$

EXPLANATION

The general term of the arithmetic sequence is

$a_n=1+\frac{5}{2}n$

For the first term,we substitute $n=1$ to get,

$a_1=1+\frac{5}{2}\times 1$

$a_1=1+2.5=3.5$

Similarly

$a_5=1+\frac{5}{2}\times 5$

$a_5=13.5$

The sum of the first n-terms is given by the formula,

$S_n=\frac{n}{2}(a_1+l)$

where l is the last term.
In this case

$l=a_5=13.5$

We substitute these values to get,

$S_5= \frac{5}{2} (3.5 + 13.5)$

$S_5= \frac{5}{2} (17)$
$S_5=42.5$

We could have also used the formula,

$S_n=\frac{n}{2}(2a_1+(n-1)d)$

$S_5=\frac{5}{2}(2(3.5)+(5-1)2.5)$

$S_5=42.5$
