Answer:

<u>Use Pythagorean:</u>

a² + b² = c²

x² = 13² - 5²
x² = 144
x = √144
x = 12

x² = 7² + 4²
x² = 65
x = √65
Option D

x² = 10² - 6²
x² = 36
x = √36
x = 6

Solve for x and y in the given the 45° - 45° - 90° triangle shown above. When applicable, simplify all radicals and show your wo

vazorg [7]

Answer:

Therefore,

$x=y= 4\sqrt{2}=5.6568\ units$

Step-by-step explanation:

Given:

Consider In Right Angle Triangle ABC

∠B = 90°

∠C = ∠A = 45°

AB = y

BC = x = adjacent side

AC = 8 = hypotenuse

To Find:

x = ?

y = ?

Solution:

In Right Angle Triangle ABC by Cosine Identity we have

$\cos C = \dfrac{\textrm{side adjacent to angle C}}{Hypotenuse}\\$

substituting the above given values we get

$\cos 45 = \dfrac{BC}{AC}=\dfrac{x}{8}$

$\dfrac{1}{\sqrt{2} } =\dfrac{x}{8}\\\therefore x=\dfrac{8}{\sqrt{2} } \\Rationalizing\ we\ get\\\therefore x=\dfrac{8}{\sqrt{2}}\times \dfrac{\sqrt{2} }{\sqrt{2}}}\\\therefore x=4\sqrt{2}=4\times 1.4142=5.6568\ units$

As The triangle is 45 - 45 - 90

It is an Isosceles Right triangle

$x=y$ ..... Isosceles Triangle property

$\therefore y=4\sqrt{2}=4\times 1.4142=5.6568\ units$

Therefore,

$x=y= 4\sqrt{2}=5.6568\ units$

Liz runs 8 feet per second. Katie runs 350 feet in 31 seconds. Katie runs 350 feet in 31 seconds. Stephanie runs 1 mile in 388 s

VikaD [51]

Answer: Stephanie is the fastest

Step-by-step explanation:

Here we have to find who runs faster:

Liz:

$8 ft/s$

Katie:

$\frac{350 ft}{31 s}=11.29 ft/s$

Stephanie:

$\frac{1 mile}{388 s}. \frac{5280 ft}{1 mile}=\frac{5280 ft}{388 s}=13.60 ft/s$

Noah:

$\frac{541 ft}{1 min}. \frac{1 min}{60 s}=9.01 ft/s$

As we can see after comparing, Stephanie is the fastest, since she travels more distance in less time.
