Mathematics
1 answer:
Leno4ka [110]1 year ago
5 0

Answer:

Step-by-step explanation:

define function fg(x) :

Fg(x)  = f(g(x))

         = \frac{5}{x} (4-2x)-1

         = \frac{20}{x} - \frac{10x}{x} - 1

         = 20 - 10x -1

         = 20 - 1 - 10x

         = 19 - 10x

Find the value of x.
melomori [17]

Answer:

The measure of angle x is 40°

Step-by-step explanation:

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

see the attached figure with letters to better understand the problem

so

m∠x=(1/2)[arc AB-arc AC]

<u><em>Find the measure of arc AC</em></u>

we know that

arc AB+arc BC+arc AC=360° ----> by complete circle

substitute the given values

arc AB=200°

arc BC=40°

arc AC=?

200°+40°+arc AC=360°

240°+arc AC=360°

arc AC=360°-240°=120°

<u><em>Find the measure of angle x</em></u>

m∠x=(1/2)[200°-120°]=40°

I will give BRAINLIEST to the correct answer <br> Find the measure of angle 6.
True [87]

Answer:

m∠6 = 116°

Step-by-step explanation:

<u>first find x:</u>

7x - 17 = 2x + 78

subtract 2x from both sides: 5x - 17 = 78

add 17 to both sides: 5x = 95

divide by 5: x = 19

<u>plug x into 7x - 17</u>

7(19) - 17 = 116

∠6 and 7x - 17 are vertical angles and therefore congruent, so m∠6 also = 116°
