The answer is

The distance from the point (x,y) to the focus, (−2,3), is (x + 2)^2+(y − 3)^2. The distance from the point (x,y) to the directrix, y=7, is |y−7|.

Answer:

1. 1458

2. 500 or -500

Step-by-step explanation:

1. a4=54, a5=162

r = 162/54 = 3

a7 = a5 × r²

= 162 × 3² = 1458

2.a4=-4, a6=-100

r² = -100/-4 = 25

r = +/- 5

a7 = a6 × r

= -100 × +/- 5

= +/- 500

Answer:

$\boxed{\boxed{\tt x=87^{\circ}}}$

Step-by-step explanation:

We know that a triangle has 3 sides, A triangle's interior angles add up to 180 degrees.

Now, let's write this as an equation:

$\tt x^{\circ}+37^{\circ}+56^{\circ}=180^{\circ}$

The missing angle is 180° minus the sum of the other two angles.

$\tt x^{\circ}=180^{\circ}-56^{\circ}-37^{\circ}$

Subtract the numbers:

$\tt 180^{\circ}-56^{\circ}-37^{\circ}=87^{\circ}$

$\tt x=87^{\circ}$
