Find the value of x picture attached

aev [14]

Answer:

Step-by-step explanation:

These angles are <em>same side interior angles</em>.

This means that (11x + 10) + (10x - 40) = 180

Solve for x:

11x + 10 + 10x - 40 = 180

21x - 30 = 180

+30 +30

21x = 210

Describe and correct the error in finding csc θ, given that θ is an acute angle of a right triangle and cos θ =7/11

a_sh-v [17]

Answer:

<h2>cosecθ = 1/sinθ = 11/6√2</h2>

Step-by-step explanation:

Given that cos θ =7/11, cosec θ = 1/sinθ in trigonometry.

Based on SOH, CAH, TOA;

cosθ = adjacent/hypotenuse = 7/11

adjacent = 7 and hyp = 11

Since sinθ = opp/hyp, we need to get the opposite to be able to calculate sinθ.

Using pythagoras theorem to get the opposite;

$hyp^{2} = adj^{2} + opp ^{2} \\opp = \sqrt{hyp^{2} - adj^{2} } \\opp = \sqrt{11^{2} - 7^{2}} \\opp = \sqrt{72} \\opp = 6\sqrt{2}$

sinθ = 6√2/11

cosecθ = 1/sinθ = 1/( 6√2/11)

cosecθ = 1/sinθ = 11/6√2

Note the error; cscθ $\neq$ 1/cosθ but cscθ = 1/sinθ

(7 x 10 ^5) + (4 x 10 ^2)

spayn [35]

$\huge\text{Hey there!}$

$\mathsf{(7\times 10^5) + (4 \times 10^2)}\\\mathsf{= 7\times 10^5 + 4 \times 10^2}$

$\large\textsf{Let's solve for the LEFT SIDE first}$

$\mathsf{7\times 10^5}\\\\\mathsf{10^5}\\\mathsf{= 10\times10\times10\times10\times10}\\\mathsf{= 100 \times 100\times 10}\\\mathsf{= 10,000 \times 10}\\\mathsf{= 100,000}\\\\\mathsf{7\times100,000}\\\mathsf{= 700,000}$

$\large\textsf{NEW EQUATION: }\bold{700,000} + {4}\times 10^2$

$\large\textsf{Now, let's solve for the RIGHT SIDE last}$

$\mathsf{4\times 10^2}\\\\\mathsf{10^2}\\\mathsf{= 10\times10}\\\mathsf{= 100}\\\\\mathsf{4\times100}\\\mathsf{= 400}$

$\large\text{NEW EQUATION: 700,000 + \bf 400}$

$\large\text{700,000 + 400}\\\\\large\text{SIMPLIFY IT!}\\\\\large\text{= 700,400}$

$\huge\text{Therefore, the answer should be: \boxed{\mathsf{700,400}}}\huge\checkmark$

$\huge\text{Good luck on your assignment \& enjoy your day!}$
