Answer:
x = 47.4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos x = 8.8 / 13
Take the inverse cos of each side
cos ^-1 ( cos x) = cos ^-1( 8.8 /13)
x = cos ^-1( 8.8 /13)
x =47.39633319
Rounding to the nearest tenth
x =47.4
Answer:
The correct option is C.
Step-by-step explanation:
The time in first figure is 3:00 pm and the time in second figure is 4:30 pm.
So total time taken by car is

It means total time taken by car is 1.5 hour.
The distance in first figure is 50 miles and the speed in second figure is 155 miles.
So total distance travelled by car is

It means total distance travelled by car is 105 miles.
The formula of speed is


Therefore option B represents the solution. Option B is incorrect.
Multiply both sides by 1.5 hours.

Therefore option D represents the solution. Option D is incorrect.
Divide both sides by speed.

Therefore option A represents the solution. Option A is incorrect.
Option C can not represent the solution, therefore option C is correct.
Answer:
0.23
Step-by-step explanation:
2.3% = 0.023
So 0.23*100=23% therefore larger than 2.3%

Answer: 110°
<u>Step-by-step explanation:</u>
∠A ≅ ∠B
since ∠A = 35° (given), then ∠B = 35°
Use the Triangle Sum Theorem to find ∠C:
∠A + ∠B + ∠Q = 180°
35° + 35° + ∠Q = 180°
70° + ∠Q = 180°
∠Q = 110°
The central angle (∠AQB) ≅ arc AB
since ∠AQB = 110° (solved above), then arc AB = 110°
