Answer:

a = 8, b = 3.2, c = 2.8

Step-by-step explanation:

Use the property of angle bisector:

An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.

Using the above and the diagram we can see:

a/6 = 4/3

and

a/7 = b/c

Also we have:

b + c = 6

From the first equation we find:

a = 6*4/3 = 8

And from the second equation we get:

8/7 = b/c ⇒ b = 8/7c

Substitute b in the third equation:

8/7c + c = 6
15/7c = 6
c = 42/15 = 2.8

Then, find b:

b = 6 - 2.8 = 3.2

Answer:

The answer is 53 or Square Root (sqrt) of 2809

Step-by-step explanation:

a^2+b^2=c^2

28^2+45^2=c^2

784+2025=c^2

c^2=sqrt 2809

c = 53

Help someone how do you solve this

Flauer [41]

Answer:

a = 10/3

Step-by-step explanation:

This can be written as:

$x^{2} (x^{4})^{1/3} = x^{a}$

Anything to the power of 1/3 means to find the cube root. We can simplify this to:

$x^{2} (x^{4/3}) = x^{a}$

I just multiplied 4 and 1/3 (because of the second index law $(a^{m})^{n} = a^{mn}$ ). Now, we can add the powers because the bases are the same and we are multiplying (first index law):

$x^{10/3} = x^{a}$

a = 10/3

Hope this helps!

Question 134 (plz help) (ps I luv u)

stiv31 [10]

Answer:

<B = 108 degrees

Step-by-step explanation:

<A = (Alternate Angles are congruent)

So,

6x+18 = x+93

=> 6x-x = 93-18

=> 5x = 75

Dividing both sides by 5

=> x = 15

Now,

<B = x+93

=> <B = 15+93

=> <B = 108 degrees

☆pls help no one has helped me and I'm so confused!

Answer:

Step-by-step explanation:

a). $\frac{5\pm\sqrt{-4}}{3}$ = $\frac{5}{3}\pm \frac{\sqrt{-4}}{3}$

= $\frac{5}{3}\pm\frac{2\sqrt{(-1)} }{3}$

= $\frac{5}{3}\pm\frac{2i}{3}$ [Since, i = $\sqrt{(-1)}$ ]

b). $\frac{10\pm\sqrt{-16}}{2}$ = $\frac{10}{2}\pm \frac{\sqrt{-16}}{2}$

= $5\pm \frac{4\sqrt{-1}}{2}$

= 5 ± 2i [Since, i = $\sqrt{(-1)}$ ]

c). $\frac{-3\pm \sqrt{-144}}{6}$ = $-\frac{3}{6}\pm \frac{\sqrt{-144}}{6}$

= $-\frac{3}{6}\pm \frac{12\sqrt{-1}}{6}$

= $-\frac{1}{2}\pm 2\sqrt{-1}$

= $-\frac{1}{2}\pm 2i$ [Since, i = $\sqrt{(-1)}$ ]
