Step-by-step explanation:

The coordinates of point A (2,8) and C (5,2)

The measure of segment AC

$\sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} }$

$\sqrt{ {(5 - 2)}^{2} + {(2 - 8)}^{2} }$

$\sqrt{ {(3)}^{2} + {( - 6)}^{2} }$

$\sqrt{9 + 36}$

$\sqrt{45}$

HELP PLEASE <br> solve the right triangle

aleksandrvk [35]

Answer:

Part 1) $FG=4.4\ units$

Part 2) $EF=3.9\ units$

Part 3) $m\angle G=63^o$

Step-by-step explanation:

step 1

Find the measure of length side FG

In the right triangle EFG

we know that

$sin(27^o)=\frac{GE}{FG}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(27^o)=\frac{2}{FG}$

$FG=\frac{2}{sin(27^o)}=4.4\ units$

step 2

Find the measure of length side EF

In the right triangle EFG

we know that

$cos(27^o)=\frac{EF}{FG}$ ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

$cos(27^o)=\frac{EF}{4.4}$

$EF=cos(27^o)(4.4)=3.9\ units$

step 3

Find the measure of angle G

we know that

$m\angle G+27^o=90^o$ ---> by complementary angles in a right triangle

$m\angle G=90^o-27^o=63^o$

Nata [24]

Answer:

(sqrt(x) +1)(sqrt(x)-2)

Step-by-step explanation:

$x - 2 \sqrt{x} + \sqrt{x} - 2 \\ \sqrt{x} ( \sqrt{x} - 2) + 1( \sqrt{x} - 2 ) \\ ( \sqrt{x} + 1)( \sqrt{x} - 2)$

Can u help sold this

solong [7]

Answer:

Step-by-step explanation:

To calculate the slope or gradient we use this formula:

Slope = y2-y1/x2-x1

(-3,2) = (x1, y1)

(4,2) = (x2, y2)

Slope = 2-2/4-(-3) = 0
