Solve for x. Show your work.

Answers

Answer 1

Answer:

x=6

Step-by-step explanation:

Both Angles are commentary and have a sum of 90

Therefore, set your formula up as

90 = 5x + (x + 54)

90 = 6x + 54

90 - 54 = 6x

36 = 6x

36/6 = x

6 = x

Answer:

t° = 11° s°= 71°

Step-by-step explanation:

79° + t° =90° (Given)

t°= 90° - 79°

t°= 11°

s°+79°+11°+19° =180° (angles on an str line)

s° = 180° - 109°

s° = 71°

A student began a proof of the law of sines using triangle xyz. His work is shown. The student has ____ started the proof. The next step in the proof is to ____. Then the student should _____.

Answers

To correctly prove the law of sines in a triangle the student should begin with the most basic or evident piece of information, then add related statements to it. and finish the proof with the conclusion or re-statement of the law.

What does it mean to prove in Mathematics?

A mathematical proof refers to a set of statements that logically demonstrate a law is true or the mathematical statement is valid, which means the prepositions and conclusion are valid.

How to write a proof?

The general pattern for proof is:

Write down the law or expression that you want to prove.Add statements that show the expression or law as valid by starting with the simplest or most evident reason and moving to more complex reasons.Re-state the law or conclude the statement is valid.

Note: This question is incomplete because the proof is missing; due to this I answered it based on general knowledge.

Answer:

x = 9

(5x9) - 1° = 45 - 1 or 44°

Step-by-step explanation:

the little square indicates the angle is a right angle, measuring 90°

therefore, you can solve for 'x' by creating this equation:

46 + 5x-1 = 90

45 + 5x = 90

5x = 45

x = 9

sin(A) = 7/25cos(A) = 24/25tan(A) = 7/24

==============================================

Explanation:

We use these rules shown below

sin(angle) = opposite/hypotenusecos(angle) = adjacent/hypotenusetan(angle) = opposite/adjacent

For reference angle A, the side opposite it is BC = 7 which is as far as possible we can go from this angle. The closest we can get is AB = 24 which is the adjacent side. The hypotenuse is always the longest side, always opposite the largest angle (90 degrees).

Each fraction in bold shown above is reduced as much as possible. For example, 7/24 cannot be reduced since 7 and 24 have no factors in common other than 1.

Use SOH CAH TOA
for Sin it is opp over hyp
Cos = adjacent side over hyp
Then for Tan it's opposite over adjacenct
