Since you know that the angles in a triangle add up to 180°, you can solve for x by making it an equation:
2x + x + 14 + x - 38 = 180
4x - 24 = 180
+ 24
4x = 204
÷ 4
x = 51
Now you can substitute x in to the angles
51 × 2 = 102°
51 + 14 = 65°
51 - 38 = 13°
I hope this helps!

First you would need to solve x.
2x+x+14+x-38=180
4x-24=180
4x=204
x=51
Now plug in the x for all three angle measures.
2(51)=102 degrees
51+14=65 degrees
51-38=13 degrees
Final answer is 102 degrees, 65 degrees, 13 degrees

A parallelogram has a base of 7 meters and a height of 10 meters. What is the area of the parallelogram in square meters?

3241004551 [841]

Step-by-step explanation:

Area of a parallelogram = H * B

Where ;H = height and B = 7

From the question our height = 10m and base = 7m

<h3>placing in formula</h3>

H * B

= 10m * 7m

=70m²

Therefore the area of the parallelogram is 70m²

A square and a rectangle have the same perimeter. The square has a side length of 8x units. The rectangle has a length of (5x+8)

nevsk [136]

Answer:

The perimeter of both figures is equal to $64\ units$

Step-by-step explanation:

step 1

we know that

The perimeter of a square is equal to

$P=4b$

where

b is the side length of the square

we have

$b=8x\ units$

substitute

$P=4(8x)=32x\ units$

step 2

we know that

The perimeter of a rectangle is equal to

$P=2(L+W)$

we have

$L=(5x+8)\ units$

$W=(14)\ units$

substitute

$P=2(5x+8+14)=10x+44\ units$

step 3

Equate both perimeters and solve for x

$10x+44=32x$

$32x-10x=44$

$22x=44$

$x=2\ units$

step 4

Find the perimeter of both

<em>square</em>

$P=32x=32(2)=64\ units$

<em>rectangle</em>

$P=10x+44=10(2)+44=64\ units$

How do I obtain the real number solutions to the polynomial function f(x)=x^3 - 4x^2 + x +6?

Svetlanka [38]

$\bf f(x)=x^3-4x^2+x+6\\\\
-----------------------------\\\\

\begin{array}{l|lrrrrllllll}
3&&1&-4&1&6\\
&&&3&-3&-6\\
--&&--&--&--&--\\
&&1&-1&-2&0
\end{array}\impliedby x=3\implies (x-3)=0
\\\\\\
\textit{that give us the factors of }
\\\\\\
f(x)=(x-3)(x^2-x-2)\impliedby \textit{factoring the quadratic, we get}
\\\\\\
f(x)=(x-3)(x-2)(x+1)\impliedby \textit{setting f(x) to 0}
\\\\\\
0=(x-3)(x-2)(x+1)\implies 
\begin{cases}
x-3=0\to &x=3\\
x-2=0\to &x=2\\
x+1=0\to &x=-1
\end{cases}$

so.... notice, using the p/q factors, we ended up using 3/1 or just 3, so the root of x = 3, which gives us the factor of x-3 then

then you factor the quadratic, then set f(x) to 0, and solve each for "x"
