Answer:

x = 2/3

Step-by-step explanation:

sin²30° + cos²30° + x.tan²60° = cot²30°​

=> (1/2)² + (√3/2)² + x(√3)² = (√3)²

=> 1/4 + 3/4 + 3x = 3

=> 3x = 2

=> x = 2/3

On a spinner P (3)=2/3 and the p (4)=1/8. what is the probability of getting 3 or 4
bagirrra123 [75]
For the probability of one thing or another, you add the two probabilities together. In that case, the probability of getting 3 or 4 is (2/3) + (1/8) = 19/24

Geometry, Multiple choice. Answer all if possible. Ty
Eddi Din [679]

Question 2: The answer is A. 90, 45, 45 because one angle is a right angle which is always 90 degrees and the two remaining angles are the same. Also, all triangles have to have a total amount of 180 degrees when all angle-degree-measurements are combined, which leaves A as the only possible answer.

Question 3: The answer is D. To solve this question you simply multiply all the dimensions of the triangular prism together. That would be:                                 10 x 14 x 8 = 1,120 in squared

Question 4: Sorry, didn't get this one :(

Question 5: The answer is B. 4pi. Sorry, don't have a good explanation for this one, but I'm pretty sure it is correct.

Question 6: Can't see the question, so I can't help you :(

Question 7: The answer is A. 5 feet. Using the power of elimination you can conclude that the three other options to the answer are improbable.

Question 8: The answer is B. 180 - x. To get this you need to know that 180 degrees is a flat line angle. Since angle x and angle y stem from the same two flat lines intersecting diagonally, you can determine the 180 - angle x would equal angle y.
