For the following right triangle, find the side length x

Mathematics
1 answer:
Liula [17]1 year ago
7 0

Answer:

26

Step-by-step explanation:

To find the side length of a right triangle with the other two sides already, known, use the <em>Pythagorean Theorem, </em>

a²<em> </em>+ b² = c²

or

24² + 10² = x²

24 times 24 is 576,

10 times 10 is 100,

Add them together to get 676,

And then find the square root.

√676 = 26 :)

What is the measurement of ∠2 and ∠11?
notsponge [240]

Answer:

180

Step-by-step explanation:

You measure the size of an angle with a protractor. Or could be shown by an arc on the figure to indicate which angles that are congruent. Two angles whose measures together are 180° are called supplementary e.g. two right angles are supplementary since 90° + 90° = 180°.

Trella alcala deposited 1,950 in a new credit union savings account on the first of the quarter the principal earns 4.25 percent
mrs_skeptik [129]
Amount in compound interest = p(1 + r/t)^nt where p is the initial deposit, r = rate, t = number of compunding in a period and n = period.

Here, Amount after 6 months (0.5 year) = 1,950(1 + (4.25/100)/4)^(0.5 x 4) = 1,950(1 + 0.0425/4)^2 = 1,950(1 + 0.010625)^2 = 1,950(1.010625)^2 = 1,950(1.0213629) = $1,991.66

Compound interest = Amount - principal (initial deposit) = $1,991.66 - $1,950 = $41.66

<h3>Answer:  A.  18*sqrt(3)</h3>

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

Explanation:

We'll need the tangent rule

tan(angle) = opposite/adjacent

tan(R) = TH/HR

tan(30) = TH/54

sqrt(3)/3 = TH/54 ... use the unit circle

54*sqrt(3)/3 = TH .... multiply both sides by 54

(54/3)*sqrt(3) = TH

18*sqrt(3) = TH

TH = 18*sqrt(3) which points to <u>choice A</u> as the final answer

----------------------

An alternative method:

Triangle THR is a 30-60-90 triangle.

Let x be the measure of side TH. This side is opposite the smallest angle R = 30, so we consider this the short leg.

The hypotenuse is twice as long as x, so TR = 2x. This only applies to 30-60-90 triangles.

Now use the pythagorean theorem

a^2 + b^2 = c^2

(TH)^2 + (HR)^2 = (TR)^2

(x)^2 + (54)^2 = (2x)^2

x^2 + 2916 = 4x^2

2916 = 4x^2 - x^2

3x^2 = 2916

x^2 = 2916/3

x^2 = 972

x = sqrt(972)

x = sqrt(324*3)

x = sqrt(324)*sqrt(3)

x = 18*sqrt(3) which is the length of TH.

A slightly similar idea is to use the fact that if y is the long leg and x is the short leg, then y = x*sqrt(3). Plug in y = 54 and isolate x and you should get x = 18*sqrt(3). Again, this trick only works for 30-60-90 triangles.
