Answer:
missing side: 133 cm
Explanation:
Provided <u>2 length sides</u> and <u>one angle</u> also need to find <u>one missing side</u>.
So, use cosine rule:
⇒ a² = b² + c² - 2bc cos(A)
<u>Insert values</u>
⇒ g² = 166² + 147² - 2(166)(147) cos(50)
⇒ g² = 17794.3935
⇒ g = √17794.3935
⇒ g = 133.3956
⇒ g = 133 (rounded to nearest whole number)
The answer is 36/49.
You take the second fraction and flip it (it will be 12/14) and you multiply straight across. You get 72/98. You simplify it by finding it's greatest common factor (in this case it is 2) so you divide it the numerator and the denominator by 2. You get 36/49.
Answer:
∠ B = 85°
Step-by-step explanation:
the inscribed angle B is half the measure of its intercepted arc AC , then
∠ B = 
× 170° = 85°
This is a formula if you need one. DON'T forget to cross-multiply
3/4 = x/12
Answer:
The answer is 77
Step-by-step explanation:
So, first put them in number order: 65, 73, 77, 77, 81, 83, 98. Then, we cross out the first and the last number. Now the numbers we have are 73, 77, 77, 81, 83. Then, we do that again. 77, 77, 81. One more time. 77 is the number we have left. Easy, right?
