This is an isosceles triangle: a triangle with two sides equals.
Therefore:
side BA=side CA
8x-4=5x+11

8x-5x=11+4
3x=15
x=15/3
x=5

length of side BC=4x-2=4(5)-2=20-2=18.

The lenght of side BC is 18 units of lenth.

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER

ozzi

Answer:

$\sf x=\boxed{18.21}$

Step-by-step explanation:

Assuming this is a right triangle.

<u>Trigonometric ratios</u>

$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$

where:

$\theta$ is the angle
O is the side opposite the angle
A is the side adjacent the angle
H is the hypotenuse

Given:

$\theta$ = 35°
O = x
A = 26

$\implies \sf \tan(35^{\circ})=\dfrac{x}{26}$

$\implies \sf x=26\tan(35^{\circ})$

$\implies \sf x=18.20539599...$

Therefore, x = 18.21 (nearest hundredth)

Which of the following is the equation for x: ax^2 = bx? select all that apply.

klio [65]

Answer:

• x = 0

• x = b/a

Step-by-step explanation:

Subtract the term on the right and factor:

ax^2 -bx = 0

x(ax -b) = 0

The zero product rule lets you write this as two equations:

x = 0

ax -b = 0

The latter can be rearranged to ...

ax = b

x = b/a

Of the choices shown, the equations for x are ...

x = 0

x = b/a

The monthly fees for the local pool are $8 per month

Liono4ka [1.6K]

Given:

Monthly fees for the local pool are $8 per month and $2 per visit.

Hector pays $34 in pool fees total for the month.

To find:

The number of times he visit the pool.

Solution:

We have,

Monthly fee of pool = $8

Additional fee = $2 per visit

Let Hector visit x times.

Additional fee for x times = $2x

Total fee = Monthly fee + Additional fee

$34=8+2x$

$34-8=2x$

$26=2x$

Divide both sides by 2.

$\dfrac{26}{2}=x$

$13=x$

Therefore, Hector visit the pool 13 times.
