Answer:
x=2
Step-by-step explanation:
9x+11=29
9x=29-11
9x=18
x=2
For future reference, you could use Desmos for graphs. but should be (1,1)
Given:
m∠APB = 74°
To find:
The measure of ACB
Solution:
The measure of the central angle is congruent to the measure of the intercepted arc.
⇒ m(ar AB) = m∠APB
⇒ m(ar AB) = 74°
The complete angle of the circle is 360°.
⇒ m(ar ACB) + m(ar AB) = 360°
⇒ m(ar ACB) + 74° = 360°
Subtract 74° from both sides.
⇒ m(ar ACB) = 286°
The measure of arc ACB is 286°.
Four and two hundred ninety-three thousandths
Answer:
198 km
Step-by-step explanation:
The speed of the boat supposed to be x km/h
(x+2)*9 = (x-2)*11
9x + 18 = 11x – 22
2x = 40
X = 20
Distance between 2 places: (20 + 2) * 9 = 198 km
Or (20 – 2 ) * 11 = 198 km
