Answer:

Step-by-step explanation:

Substitute x = 5 and x = 9 into f(x) and equate

f(5) = (5 - b)² = 25 - 10b + b²

f(9) = (9 - b)² = 81 - 18b + b²

Then equating the 2 gives

b² - 10b + 25 = b² - 18b + 81 ( subtract b² - 18b from both sides )

8b + 25 = 81 ( subtract 25 from both sides )

8b = 56 ( divide both sides by 8 )

b = 7

Then

f(x) = (x - 7)² and

f(1) = (1 - 7)² = (- 6)² = 36 → B

an isosceles triangle has angle measures of 55, 55, and 70. the side across the 70 degree angle is 10 inches long. how long are

Shtirlitz [24]

Answer:

The other sides of triangles are 8.72 in and 8.72 in

Step-by-step explanation:

In a triangle ABC. Please find the attachment for figure.

$\angle A=70^{\circ}$

$\angle B=\angle C=55^{\circ}$

Side BC=a = 10 in

Using sine law of trigonometry,

$\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}$

Substitute the given value into formula.

$\dfrac{10}{\sin 70}=\dfrac{b}{\sin 55}=\dfrac{c}{\sin 55}$

$\dfrac{10}{\sin 70}=\dfrac{b}{\sin 55}$

Cross multiply and we get

$b=\sin 55\times \dfrac{10}{\sin 70}$

$b=8.72$ in

It is a isosceles triangle. Therefore, b=c=8.72 in

Hence, The other sides of triangles are 8.72 in and 8.72 in
