Answer:

Look below.

Step-by-step explanation:

You need to use the Pythagorean theorem.

Formula: a^2+b^2=c^2

a=10 b=6 c=?

10^2+6^2=c^2

c≈11.6619

Their isnt any choice that has this number but if you put option D into the calculator you will get 11.66 which is correct. Option D is correct for side A.

If an altitude is drawn from the right angle of a right triangle to its hypotenuse, the two segments formed on the hypotenuse ar

valentina_108 [34]

Answer:

the length of the altitude is 7.5 cm

Step-by-step explanation:

In a Δ ABC, $\overline {BC}$ is the altitude

If an altitude is drawn to the hypotenuse of the right angle triangle as shown in the image attached below; Then:

$(AD)^2 = AD*AC \\ \\ x^2 = 5*11.25 \\ \\ x^2 = 81.25 \\ \\ x = \sqrt{81.25} \\ \\ x= 9.01$

NOW;

$(BC)^2 = DC*AC \\ \\ z^2 = 11.25 *16.25 \\ \\z^2 = 182.8125 \\ \\ z= \sqrt{182.8125} \\ \\ z= 13.52$

Finally; the altitude which is $\overline {BD}$ is calculated as:

$(BD)^2 = AD*DC \\ \\ y^2 = 5*11.25 \\ \\ y^2 = 56.25 \\ \\ y = \sqrt{56.25} \\ \\ y= 7.5$

Thus; the length of the altitude is 7.5 cm

_ x 2 + 1 = 25<br><br> Pls help I need the answer

WITCHER [35]

Answer:

x = ± 2 $\sqrt{6}$

Step-by-step explanation:

x² + 1 = 25 ( subtract 1 from both sides )

x² = 24 ( take square root of both sides )

x = ± $\sqrt{24}$ = ± $\sqrt{4(6)}$ = $\sqrt{4}$ × $\sqrt{6}$ = ± 2 $\sqrt{6}$

x = - 2 $\sqrt{6}$ , x = 2 $\sqrt{6}$
