Step-by-step explanation:

<em>The image if the circle and triangle can be found online</em>

Given

$JA = 8$

$AL = 8$

$CK = 10$

Required

The perimeter of JKL

Since the mid-points of the tangents are A, B and C respectively.

$JK = JB + BK$

Where

$JB = JA = 8$

$BK = CK = 10$

So:

$JK =8+10 =18$

$JL = JA + AL$

$JL = 8+11 = 19$

$KL = CL + CK$

Where

$CL =AL = 11$

So:

$KL = 11+10 = 21$

So, the perimeter (P) is:

$P = JK+ KL +JL$

$P = 18 + 19 + 21$

$P = 58$

Write the expression as the sine, cosine, or tangent of an angle.

sin({{ \alpha}} + {{ \beta}})=sin({{ \alpha}})cos({{ \beta}}) + cos({{ \alpha}})sin({{ \beta}})
\\ \quad \\
\boxed{sin({{ \alpha}} - {{ \beta}})=sin({{ \alpha}})cos({{ \beta}})- cos({{ \alpha}})sin({{ \beta}})}$

$\bf cos({{ \alpha}} + {{ \beta}})= cos({{ \alpha}})cos({{ \beta}})- sin({{ \alpha}})sin({{ \beta}})
\\ \quad \\
cos({{ \alpha}} - {{ \beta}})= cos({{ \alpha}})cos({{ \beta}}) + sin({{ \alpha}})sin({{ \beta}})\\\\
-------------------------------\\\\
sin(48^o)cos(15^o)-cos(48^o)sin(15^o)\implies sin(48^o+15^o)
\\\\\\
sin(63^o)$

Help with this math question... Leslie created a rectangle on the coordinate plane. Three of the vertices are (5,-2), (5,2), (2,

Aloiza [94]

Draw the points on a graph, you will have three points and need to add the fourth to make the corners of a rectangle. After you have found the point on the missing corner of the rectangle see what its x and y coordinates are.

The answer is: (2, -2)
