The Answer is Height: hb = 12.923

Acute scalene triangle.Sides: a = 15 b = 13 c = 14

Area: T = 84
Perimeter: p = 42
Semiperimeter: s = 21

Angle ∠ A = α = 67.38° = 67°22'49″ = 1.176 rad
Angle ∠ B = β = 53.13° = 53°7'48″ = 0.927 rad
Angle ∠ C = γ = 59.49° = 59°29'23″ = 1.038 rad

Height: ha = 11.2
Height: hb = 12.923 <- Answer
Height: hc = 12

Median: ma = 11.236
Median: mb = 12.971
Median: mc = 12.166

Inradius: r = 4
Circumradius: R = 8.125

Vertex coordinates: A[14; 0] B[0; 0] C[9; 12]
Centroid: CG[7.667; 4]
Coordinates of the circumcenter: U[7; 4.125]

Convert the complex number z = 4 - 10i from rectangular form to polar form.

mrs_skeptik [129]

ANSWER

$r = 2 \sqrt{29} ( \cos(292 \degree) + \sin(292 \degree))$

EXPLANATION

The polar form of a complex number ,

$z = x + yi$

is given by:

$z = r( \cos( \theta) + i \sin( \theta) )$

where

$r = \sqrt{ {x}^{2} + {y}^{2} }$

The given complex number is:

$z = 4 - 10i$

$r = \sqrt{ {4}^{2} + {( - 10)}^{2} }$

$r = \sqrt{16 + 100}$

$r = \sqrt{116} = 2 \sqrt{29}$

And

$\theta= \tan^{ - 1}(\frac{ y}{x} )$

$\theta= \tan^{ - 1}(\frac{ - 10}{4} )$

$\theta= 292 \degree$

Hence the polar form is :

$r = 2 \sqrt{29} ( \cos(292 \degree) + \sin(292 \degree))$

Is anyone good with this? I need help finding the answer.

dybincka [34]

To solve this problem, we have to find the perimeter of the shape.
we already know that two of the sides are 82m, all we need to do is find the circumference of the semicircles.
to find circumference, you multiply the diameter of a circle by pi. since we have two identical semicircles, we have one full circle. 66•3.14=207.24
207.24+82+82=371.24
the answer is 371.24m
