Mathematics
2 answers:
Hoochie [10]2 years ago
4 0

Answer:

Angles 2 and 1

Step-by-step explanation:

Complementary angles are angles that sum to 90° or form a right angle. In this case, the right angles are 3 and 4, but the two angles that FORM a right angle are angles 2 and 1.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

<u>Answer:</u>

  • ∠2 and ∠1

<u>Explanation:</u>

  • Complementary angles - Angles such that two angles form a right angle.

The only angle that forms a complementary angle pair is ∠2 and ∠1 because both angles form a right angle.

<u>Hence, ∠1 and ∠2 are complementary angles.</u>

Alex777 [14]

Complete question :

A zoologist is interested in whether climate affects how high kangaroos can jump. In a random sample of gray kangaroos from an Australian forest, he found the mean jump height was x¯=286 inches with a margin of error of 15 inches.

Construct a confidence interval for the mean jump height of gray kangaroos.

Answer:

(271, 301)

Step-by-step explanation:

Given that:

Mean (x¯) = 286

Margin of Error = 15 inches

The confidence interval :

(Mean - Margin of Error), (mean + margin of error)

(286 - 15), (286 + 15)

(271, 301)

Hence confidence interval equals : (271, 301)

How do I simplify this (sinx)/(secx+1)
pochemuha

Answer:

Step-by-step explanation:

\frac{sin~x}{sec~x+1} =\frac{sin~x}{\frac{1}{cos~x}+1  } =\frac{sin~x~cos~x}{1+cos~x} \\=\frac{sin~x~cos~x}{1+cos~x} \times \frac{1-cos~x}{1-cos~x} \\=\frac{sin~x~cos~x(1-cos~x)}{1-cos^2 x} \\=\frac{sin~x~cos~x(1-cos~x)}{sin^2x} \\=\frac{cos~x(1-cos~x)}{sin~x} \\=cos ~x(csc~x-cot~x)\\or\\=cot~x(1-cos~x)
