Answer:

See Explanation

Step-by-step explanation:

\overrightarrow{KH} \: bisects \: \angle GKJ (Given)

\therefore \angle GKH \cong \angle HKJ (angle bisector theorem)

\therefore m\angle GKH = m\angle HKJ

\implies m \angle 11 =m \angle 12

m\angle 9 + m\angle 12 = 180\degree.... (1)(Linear pair angles)

&

m\angle 10 + m\angle 11 = 180\degree(Linear pair angles)

\implies m\angle 10 + m\angle 12 = 180\degree.... (2) (\because m \angle 11 = m\angle 12)

From equations (1) & (2)

m\angle 9 + \cancel {m\angle 12} =m\angle 10 +  \cancel {m\angle 12}

\therefore m\angle 9  =m\angle 10

\implies \huge \orange {\angle 9  \cong \angle 10}

Thus proved

In a right triangle, if a = 8 and c = 17, what is the correct setup to find the value of b?
salantis [7]

Answer:

b =15

Step-by-step explanation:

We can use Pythagoras theorem to find b:

a^{2}+b^{2} = c^{2}

8^{2} + b^{2} = 17^{2}

64 + b^{2} = 289

64 + 225 = 289

64 + 15^{2} = 289

b = 15

hope this helps :) and sorry if not right

How many times does the equation f(x)=2x^2+9x-5 intersect the x-axis
Komok [63]

Answer:

2

Step-by-step explanation:

f(x)=2x^2+9x-5

When we are find how many times it intersects the x axis, we are finding the zero's. Set the equation equal to zero

0=2x^2+9x-5

Factor the equation

0 = (2x+1) (x-5)

2*1

1*-5 = -5

2*-5 +1*1 = -9

This checks for the first last and middle terms so we factored correctly

Then using the zero product property

2x+1 = 0 and x-5 =0

2x = -1    x=5

x = -1/2  and x=5

This function crosses the x axis 2 times
