What is the value of x? Enter your answer in the box.

X = 9

Since it is a equilateral triangle, the all sides should be 60 degrees. Set one equation to 60 and you would get x = 9.

ASAP please help please!!!

Here, ∠1 and ∠2 are complementary angles which means they together are forming a right angle or we can also say that their sum is 90°.So, According to this:

$\sf∠1 + ∠2 = 90$

∠1 = x-8
∠2 = 6x

$\sf \: x - 8 + 6x = 90$

$\sf \: 7x - 8 = 90$

$\sf \: 7x = 90 + 8$

$\sf \: 7x = 98$

$\sf \: x = 14$

<h3>Now, </h3>

$\tt∠1 = x - 8 \\ \tt = 14 - 8 \\ \tt = 6$
$\tt \: ∠2 = 6x \\ \tt = 6 \times 14 \\ \tt = 84$

<em>Thus, The measure of m∠1 is 6° and measure of m∠2 is 84°...~</em>

Solve x2 + 2x = 4 for x by completing the square. x equals plus or minus square root of 5 plus 1 x equals plus or minus square r

steposvetlana [31]

Answer:

x equals plus or minus square root of 5 minus 1

Step-by-step explanation:

we have

$x^{2} +2x=4$

Divide by 2 the coefficient of the x-term

$2/2=1$

squared the number

$1^2=1$

Adds both sides

$x^{2} +2x+1=4+1$

$x^{2} +2x+1=5$

Rewrite as perfect squares

$(x+1)^{2}=5$

take the square root both sides

$x+1=(+/-)\sqrt{5}$

$x=(+/-)\sqrt{5}-1$

therefore

x equals plus or minus square root of 5 minus 1
