The other 2 angles of given right angles are 61.93° and 28.072°, if a triangle with side lengths 8, 15, and 17 is a right triangle by the converse of the Pythagorean Theorem.

Step-by-step explanation:

The given is,

                  Right angled triangle,

                  Side lengths are 8, 15, and 17  

Step:1

                 The given triangle is right angle triangle by the converse of Pythagorean theorem, so the trigonometric ratio,

                Ref the attachment,

                For angle a,

                             Sin a = \frac{Opp}{Hyp}...................................................(1)

                  Where,  Opp - 8

                                 Hyp - 17

                  From equation (1),

                                       = \frac{8}{17}

                                       = 0.470588

                                       = sin^{-1}(0.470588)

                                    a = 28.072°

                     For angle b,

                                   Sin a = \frac{Opp}{Hyp}...................................................(1)

                  Where,  Opp - 15

                                 Hyp - 17

                  From equation (1),

                                       = \frac{15}{17}

                                       = 0.882352

                                       = sin^{-1}(0.882352)

                                    b = 61.93°

Step:2

           Check for solution for right angle triangle,

                         90 ° = Other 2 angles

                         90 ° = a + b

                         90 ° = 28.072° + 61.93°

                         90 ° = 90 °

Result:

           The other 2 angles of given right angles are 61.93° and 28.07°, if a triangle with side lengths 8, 15, and 17 is a right triangle by the converse of the Pythagorean Theorem.

the point 3,2 lies on a circle.what is the exact length of the radius of this circle if the center is located at (-1,-4)
Crazy boy [7]
You can use the distance formula to solve this.

Distance Formula:
d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}

I am going to use point (3,2) as point 1 and (-1,-4) as point 2
Insert the points into the formula
d = \sqrt{(X_2 -X_1)^2 + (Y_2 - Y_1)^2}
d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}
Solve:
d = \sqrt{((-1) - 3)^2 + ((-4) - 2)^2}
d = \sqrt{(-4)^2 + (-6)^2}
d = \sqrt{16 + 36}
d = \sqrt{52}
d = \sqrt{52} = \sqrt{4}\sqrt{13}
d = \sqrt{52} = 2 \sqrt{13}
d = 2 \sqrt{13}
radius = 2 \sqrt{13} = 7.2111

Find the slope of the curve r=cos(2theta) at theta=pi/6.. . Must this be solved parametrically? If so, why?
lara31 [8.8K]

By converting into parametric equations,

<span><span>x(θ)=r(θ)cosθ=cos2θ<span>cosθ
</span></span><span>y(θ)=r(θ)sinθ=cos2θsinθ</span></span>

By Product Rule,

<span>x'(θ)=−sin2θcosθ−cos2θsinθ</span>

<span>x'<span>(π/2)</span>=−<span>sin(π)</span><span>cos<span>(π/2)</span></span>−<span>cos(π)</span><span>sin<span>(π/2)</span></span>=1</span>

<span>y'(θ)=−sin2θsinθ+cos2θcosθ</span>

<span>y'<span>(π/2)</span>=−<span>sin(π)</span><span>sin<span>(π/2)</span></span>+<span>cos(π)</span><span>cos<span>(π/2)</span></span>=0</span>

So, the slope m of the curve can be found by

<span>m=<span>dy/dx</span><span>∣<span>θ=<span>π2
</span></span></span>= <span><span>y'<span>(π/2)/</span></span><span>x'<span>(π/2)
</span></span></span></span>=0/1

Answer:

a  4 1/5

b  7 7/24

Step-by-step explanation:

a  7/9 * 5 2/5

Change the mixed number to an improper fraction

7/9 * (5*5+2)/5

7/9 * 27/5

Rewrite

7/5 * 27/9

7/5 * 3

21/5

Change this back to a mixed number

5 goes into 21 4 times  (4*5 = 20 ) with 1 left over

4 1/5


b  1 3/4 * 4 1/6

Change to improper fractions

(4*1+3)/4  * (6*4+1)/6

7/4 * 25/6

175/24

Change back to a mixed number

24 goes into 175 7 times  (7*24 =168 ) with 7 left over

7 7/24
