If sine of x equals square root of 2 over 2, what is cos(x) and tan(x)? Explain your steps in complete sentences.

Answers

Answer 1

Answer: sin $x$ = $(opposite)/(hypotenuse)$ = $( √(2) )/(2)$
opposite= $√(2)$
hypotenuse=2

$Adjacent^(2)$ + $(√(2 ))^(2 )$ = $2 ^(2)$
$Adjacent^(2)$ +2=4
$Adjacent^(2)$ =2
Adjacent= $√(2)$

cos $x$ = $(ajc)/(hyp)= ( √(2) )/(2)$
Tan $x$ = $(opp)/(adj) = ( √(2) )/( √(2) )$

The surface area of a cube is 294 cm2. Which statements are true about the same cube measured in square millimeters? Choose all answers that are correct. A. The number representing the surface area would decrease. B. The number representing the surface area would increase. C. The actual surface area would decrease. D. The actual surface area would increase. E. The actual surface area would stay the same.

Answers

The answer to the question that is being presented above would be letter E. The actual surface area would stay the same. This statement is true because although the unit of measurement is different, the actual surface area remains the same and unchanged.

The correct statements are B and E. Converting the value to millimeters, we have 29,400 mm^2. We see that the number which represents the surface area increased. However, since we still have the same cube and same dimensions, the actual surface area is still stay same.

If these two trapezoids are similar, what is the measure of the missing angle?90°
1150
900
65°
Answer:
degree.

Answers

The measure of the missing angle in the similar trapezoid is 90°.

In the given trapezoid the measure of angles are 90°, 115°, 90° and 65°.

What are similar figures?

Similar figures mean when two figures are of the same shape but are of different sizes. In other words, two figures are called similar when they both have a lot of the same properties but still may not be identical.

Given that, the two trapezoids are similar

Here, the measure of the missing angle in the other trapezoid is 90°

Therefore, the measure of the missing angle in the similar trapezoid is 90°.

WHAT is the answers to 2a 2b and 2c ?

Answers

a). The shape has 5 sides. The inside angles of every 5-sided shape (pentagon) add up to 540 degrees. The 3 angles given add up to (110 + 109 + 100) = 319 . The two leftover angles add up to (540 - 319) = 221 degrees. They're not equal, so we can't tell how the 221 breaks down between them. b). The shape has 4 sides. The inside angles of every 4-sided shape add up to 360 degrees. The 3 angles given add up to (85+ 92 + 93) = 270 degrees. The fourth angle is (360 - 270) = 90 degrees, even though it doesn't look like it. c). The shape has 6 sides. The inside angles of every 6-sided shape add up to 720 degrees. The 4 angles given add up to (120 + 110 + 105 + 110) = 445 degrees. The two leftover angles add up to (720 - 445) = 275 degrees. They're not equal, so we can't tell how the 275 breaks down between them.

In a school, the ratio of musicians to athletes is 3:1. which statement is true13 of the total students are musicians.

If there are 18 people, then 12 of them are athletes.

If there are 3 athletes, then there are 12 musicians.

The number of musicians is 3 times the number of athletes

Answers

I think the correct answer from the choices listed above is the last option. In a school, the ratio of musicians to athletes is 3:1. This means that the number of musicians is 3 times the number of athletes. Hope this answers the question. Have a nice day.

Answer: The answer is (D) The number of musicians is 3 times the number of athletes.

Step-by-step explanation: Given that the ratio of musicians to athletes in a school is 3 : 1. We are to select the correct statement out of the given four options.

Since the total number of people are not given, so we cannot say that 13 of them are musicians. Therefore, option (A) is incorrect.

If there are 18 people, then number of athletes is given by

$(x)/(x+3x)* 18=4.5\neq 12,$
