Answer:

Step-by-step explanation:

Given the expression;

19/258 = 21/x

We are to find the unknown value x;

Cross multiply;

19 * x = 258 * 21

19x = 5418

Divide both sides by 19;

19x/19 = 5418/19

x = 285.15

Hence the unknown value is 285.15

Select the representation that does not change the location of the given point. (4, 110°)

miss Akunina [59]

Answer:

(4,470°)

Step-by-step explanation:

The representation that does not change the location of (4, 110°) in polar coordinates are all points that are coterminal with the given point.

The only point among the given options that is coterminal with (4, 110°) is (4, 470)°

The two points have the same magnitude and 470°-360°=110°.

Since 110° is coterminal with 470° and the two points have the same magnitude with the same sign, the two points represent the same location in polar coordinates.

The correct choice is (4,470°)

Find the area of the figure. PLEASE HELP I NEED IT URGENT PLEASE

ale4655 [162]

Answer:

Area = Area of bigger triangle - Area of small triangle

${ \rm{area = ( \frac{1}{2} \times b_{b} \times h_{b}) - ( \frac{1}{2} \times b_{s} \times h _{s} )}} \\ \\ { \tt{area = ( \frac{1}{2} \times 18 \times 7) - ( \frac{1}{2} \times (18 - 13) \times 7) }} \\ \\ { \tt{area = (9 \times 7) - (2.5 \times 7)}} \\ \\ { \underline{ \tt{ \: \: area = 45.5 \: \: sq \: units \: \: }}}$

Area = area of square + area of two right angled triangles

${ \tt{area = (s \times s) + 2( \frac{1}{2} \times b \times h)}} \\ \\ { \tt{area = (6 \times 10) + (3 \times 5)}} \\ \\ { \underline{ \tt{ \: \: area = 75 \: \: {m}^{2} \: \: }}}$
