What is the value for y? Enter your answer in the box. y = An isosceles triangle A B C with horizontal base B C and vertex A is
vfiekz [6]

<u><em>Answer:</em></u>

x = 25

y = 14

<u><em>Explanation:</em></u>

The described scenario can be represented using the attached triangle.

<u>1- getting the value of x:</u>

We know that ΔABC is an isosceles triangle with AC = BC

<u>This means that:</u>

∠CAB = ∠CBA

We know that ∠CAB = 50° and ∠CBA = 2x°

<u>Equating the two angles, we get:</u>

50 = 2x .................> Divide both sides by 2

x = 25

<u>2- getting the value of y:</u>

We know that the sum of the internal angles of a triangle is 180°

<u>This means that:</u>

∠ABC + ∠CAB + ∠ACB = 180°

<u>We have:</u>

∠ABC = 2x = 50°

∠ACB = 5y + 10

∠CAB = 50°

<u>Now, we substitute to get the value of y as follows:</u>

50 + 50 + 5y + 10 = 180

110 + 5y = 180

5y = 180 - 110

5y = 70 .............> Divide both sides by 5

y = 14

Hope this helps :)

Question 7 (5 points)
Arada [10]

Answer: 6

That chart is confusing ash, but median just refers to the middle value. Just put them in order (4,4,6,9,12) and then find the middle. In this case it's easy as there are an odd number of values. But if you have another question where there are an odd number, for example (4,4,6,10,12,15) find the two middle numbers, 4 and 9, add them (6+10=16) and then divide by 2 to find the number in between those two. (16/2=8)

Hope this helps!

1/10 chance on winning with 1 ticket...so winning with 4 tickets = 
1/10 * 1/10 * 1/10 * 1/10 = 1/(10^4) = 1/10,000

5) If f(x) = 4x2 - 5x + 7 and g(x) = 3x2 - 2x + 8, find f(x) + g(x).
Delvig [45]
Simply put this just means add the like terms together.
f(x) + g(x) = 4x^2 - 5x +7 + 3x^2 - 2x + 8
f(x) + g(x) = 7x^2 - 7x + 15. Don't go any further.

Use the given figure to find the length of FG
bazaltina [42]

Answer:

The length of FG is 19\:units.

Step-by-step explanation:

Since the altitude of the triangle bisects the third side, triangle FGH is isosceles.


Therefore |FG|=|HG|


This implies that,

5x-6=3x+4

This is a linear equation where we easily solve for x.


We group like terms to get,

5x-3x=4+6


2x=10


We divide both sides by 2 to obtain,

x=5.


The length of FG is

5(5)-6=25-6=19
