The top letter is “L”<br> Please help!! Answer correctly and no guessing, please!

Mkey [24]

First you need to find out what K and L's angle is

Step #1: Finding L's angle number

to do this you are going to subtract 219-178=?

answer should be 41.

Step #2: Desiding if J is Larger than L

Is 219 Larger than 41? or is 41 larger than 219?

Need some help, kinda stuck

ElenaW [278]

Answer:

7/4

Step-by-step explanation:

$\displaystyle\frac{2 + \sqrt{ - 3} }{2} ( \frac{2 - \sqrt{ - 3} }{2} )~~~~~~$

Evaluate.

Solution:

Rewrite it as,

$\displaystyle\frac{2 + \sqrt{ - 1 } \sqrt{ 3} }{2} ( \frac{2 - \sqrt{ - 1} \sqrt{3} }{2} )$
$\displaystyle\frac{2 + i\sqrt{ 3} }{2} ( \frac{2 - i\sqrt{ 3} }{2} )~~~~~~$

Multiplying them,

$\displaystyle\frac{(2 + i\sqrt{ 3})\times(2 - i \sqrt{3}) }{2 \times 2}$

$\displaystyle\frac{(2 + i\sqrt{ 3})\times(2 - i \sqrt{3}) }{4}$

Applying Distributive property,

$\displaystyle\frac{2(2 + i\sqrt{ 3}) + \: i \sqrt{3} (2 - i \sqrt{3}) }{4}$

$\cfrac{2 \times 2 + 2( - i \sqrt{3} ) + i \sqrt{3}(2 - i \sqrt{3} ) }{4}$

$\cfrac{2 \times 2 + 2( - i \sqrt{3}) + i \sqrt{3} \times 2 + i \sqrt{3} ( - i \sqrt{3}) }{4}$

Combining each terms,

$\cfrac{4 - 2i \sqrt{3} + 2i \sqrt{3} + 3}{4}$
$\cfrac{ - 2i \sqrt{3} + 2i \sqrt{3} + 7 }{4}$
$\boxed{\cfrac{ 7}{4} }$

Last Choice is accurate.

a right triangle has a hypotenuse measuring 13 centimeters and one leg measuring 5 centimeters. What is the lenght in centimeter

alexandr1967 [171]

Answer:

12 cm

Step-by-step explanation:

So the Pythagorean Theorem states $a^{2} +b^{2} =c^{2}$

If we know what c and a are, we can solve for b by doing

$b = \sqrt{c^{2} - a^{2}}$

$b = \sqrt{{13^{2}-5^{2}}$

$b = \sqrt{144}$

$b = 12$
