How to find x in a triangle with exterior angles

1 answer:

8 0

Since RS and ST are congruent sides, angles SRT and STR will be equal. Also, angles STU (5x) and STR added together equals 180. Therefore angles STU and SRT will also equal 180. All that's left to do is set up the equation and solve. 5x - 30 + 5x = 180.

Miles bought a 10 ounce bag of chips. He wants to know if it's really 10 ounces, so he uses a scale and makes four measurements.

The weight seems like most accurate to me, even thought you didn't show me what type of measurement he took.

Does anyone know how to do this <br><br>csc x ( sin x + cos x) = 1 + cot x

Dima020 [189]

Explanation:

Use the identities ...

csc(x) = 1/sin(x)

cot(x) = cos(x)/sin(x)

$\csc(x)(\sin(x)+\cos(x))=1+\cot(x)\\\\\dfrac{1}{\sin(x)}(\sin(x)+\cos(x))=1+\cot(x)\\\\\dfrac{\sin(x)}{\sin(x)}+\dfrac{\cos(x)}{\sin(x)}=1+\cot(x)\\\\1+\cot(x)=1+\cot(x)$

How do I solve for the missing angle?!<br>And please include explanations on how you got the answer

Nadusha1986 [10]

Answer:

75°

Step-by-step explanation:

In triangle FBG, one angle is 36. That means the other two must total 180-36=144. Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.

In triangle JDI, one angle is 39. That means the other two must total 180-39=141. Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5

We now have 4 of the interior angles. Pentagons have an interior total of 540. 540-108-108-109.5-109.5=105

x is the supplement of 105. 180-105=75
