Answer:

$x=20.6\ in$

Step-by-step explanation:

we know that

Applying the Pythagoras Theorem

$41.2^{2} =35.7^{2} +x^{2}$

solver for x

$x^{2}=41.2^{2}-35.7^{2}$

$x^{2}=422.95$

$x=20.6\ in$

Corey flying a kite with 105 meters of string.His string makes an angle of 42 degrees with the level ground. How high is the kit

mafiozo [28]

Given:

Given that Corey is flying a kite with 105 meters of string.

The string makes an angle of 42° with the ground level.

We need to determine the height of the kite.

Height of the kite:

The height of the kite can be determined using the trigonometric ratio.

Thus, we have;

$sin \ \theta=\frac{opp}{hyp}$

From the given data, the values are $\theta=42^{\circ}$ , opp = h (height of the kite) and hyp = 105 meters.

Substituting the values, we get;

$sin \ 42=\frac{h}{105}$

Multiplying both sides of the equation by 105, we get;

$sin \ 42 \times 105=h$

$0.669 \times 105=h$

$70.245=h$

Rounding off to the nearest meter, we get;

$h=70$

Thus, the height of the kite is 70 meters.

[Help] Classify the following triangle. Check all that apply.

Sonja [21]

The triangle is obtuse since it has an angle more than 90 degrees.
It also has 2 equivalent sides that are represented by the line, meaning it is isosceles.
Therefore,
C. and E. are correct.
Do you mind giving a clickie wickie to the THANKS or MARK AS BRAINLIEST! button if anyone else answers? It would be greatly appreciated. Thank you sooo much!

Find the distance between (-1, - 3) and (8, – 3).

dimaraw [331]

Answer: d (A,B) = 9

Step-by-step explanation: d(A,B) = √(xB - xA)^2 + (yB - yA)^2

d(A,B) = √(8-(-1))^2 + (-3 - (-3))^2

d(A,B) = √81 + 0

d(A,B) = 9

4. Anna, Beate and Cindy buy a bag of 30 biscuits together. They get 10 biscuits each. But Anna has paid 80 cents, Beate 50 cent

erma4kov [3.2K]

Answer:

Option E. 6.

Step-by-step explanation:

80:50:20 or 8:5:2. 8 ÷ 15 * 30 = 16 = 16 - 10 = 6. This is the solution.

Option A. 30 + 10 = 40. Incorrect. The solution is unequal to this.
Option B. 30 + 9 = 39. Incorrect. The solution is unequal to this.
Option C. 30 + 8 = 38. Incorrect. The solution is unequal to this.
Option D. 30 + 7 = 37. Incorrect. The solution is unequal to this.
Option E. 30 + 6 = 36. Correct. The solution equals this answer.

Option E will be the answer.
