The measure of the angle formed by 2 chords that intersect inside the circle is 1/2 the sum of the chords' intercepted arcs ⇒

45 + JK = 37×2
45 + JK = 74
JK = 74 - 45
JK = 29°

JK = 2(37) - 45
JK = 74 - 45
JK = 29

answer

The perimeter of rectangular field is 260 feet. The length of the field is 10 feet more than twice the width of the field. Which

lutik1710 [3]

The answer is C. Why? Because, they said the length is 10 feet longer. 260+10=270

so it's,

L=260 W=270

You cut a sheet of paper along its diagonal, as shown. What is the length of the diagonal? Round your answer to the nearest tent

AVprozaik [17]

 FIRST OF ALL THERE IS NO FIGURE.

ELSE I AM GIVING YOU CLUE. 

LET SHEET IS RECTANGLE IN SHAPE. SO , WE ASSUME IT'S LENGTH AND BREADTH BE 'L' & 'B'.

NOW WE CAN FIND DIAGONAL BY USING PYTHAGORAS THEOREM. 

 $diagonal = \sqrt{ {l}^{2} + {b}^{2} } \: units$

The area of two similar triangles are 50dm^2 and 32dm^2. The sum of their perimeters is 117dm. What us the perimeters of each of

Kay [80]

Answer:

Perimeter of one triangle is 65 dm

Perimeter of other triangle is 52 dm

Step-by-step explanation:

Please remember the concept

If sides are in the ratio of a:b

Then the area in the ratio of $a^{2} :b^{2}$

It is given sum of their perimeter is 117.

Let the small triangle has perimeter as x.

So, perimeter of big triangle is 117-x.

So, we can set up equation as

$\frac{50}{32} =\frac{x^{2} }{(117-x)^{2} }$

Cross multiply

50(117-x)^2 =32x^2

Expand the left side

50 $(13689 -234x+x^{2} )$ = $32x^{2}$

Distribute the left side

684450-11700x+ $50x^{2}$ = $32x^{2}$

Subtract both sides $32x^{2}$ and rewrite it $18x^{2} -11700x+684450=0$

Solve this quadratic for x.

Divide both sides of the equation by 18 to simplify.

$x^{2}$ -650 x+38025=0

Now, if possible let's factor

Find two integers whose multiplication is 38025 but adds to -650.

-65 and -585 works.

So, we can rewrite it as

(x -65)(x-585) =0

Solve them using zero product property

x=65, x=585

So, x=65 works here.

So, perimeter of one triangle is 65 dm

Perimeter of other triangle is 117-65= 52 dm
