Answer:

The measure of arc AC is equal to 33°

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

∠ABC=(1/2) arc AC

substitute the values

(2.5x+4)=(1/2)(7x-2)

solve for x

5x+8=7x-2

7x-5x=8+2

2x=10

x=5

Find the measure of arc AC

arc AC=(7(5)-2)=33°

PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!<br><br> Multiply.<br><br> (7x + 3)(4x − 5)

Anni [7]

$(7x + 3)(4x -5)$

$7x*4x+7x(-5)+3*4x+3(-5)$

$7*4xx-7*5x+3*4x-3*5$

$=28x^2-23x-15$

Hope this helps!

Thanks!

What is angle F to the nearest degree?

nekit [7.7K]

Answer:

So we already knew all three sides, there are more than one way to do it, for example:

sin∠F = HG/HF = 12/13

cos∠F = GF/HF = 5/13

tan∠F = HG/GF = 12/5

ctg∠F = GF/HG = 5/12

All of them will give you the result which is approximately 67°.

If the point (b,15) lies on the straight line with equation Y=5x fonde the value of b ?

Andrej [43]

Answer:

b = 3

Step-by-step explanation:

Substitute the y- coordinate 15 into the equation , that is

15 = 5x ( divide both sides by 5 )

3 = x

This is the x- coordinate of the point , so b = 3
