Answer:
50 degrees
Step-by-step explanation:
65 times 2=130
180-130=50
Answer:
205 minutes
Step-by-step explanation:
Step one:
given data
We are told that Luca's goal is to practice violin for 300 minutes in a week
He has practiced 45 minutes and 50 minutes for Saturday and Sunday already
that is in all, 45+50= 95minutes
Required
The remaining minutes of practice
Step two:
the deficit in practice is
300-95= 205 minutes
Answer:
The correct option is Plane A because it was 27.43 miles away ....
Step-by-step explanation:
Angle of elevation of plane A=41 °
Angle of elevation of plane B=43°
height of planes=18 miles
let Δabc be the right triangle formed by the plane A and Δabd be the right triangle formed by the plane B
then ab=18miles
∠c, angle of elevation of plane A=41 °
then distance bc=?
sinc=ab/bc
sin(41°)=18/bc
bc=18/0.65
bc=27.437 miles
Now
∠d, angle of elevation of plane B=43°
then distance bd=?
sinc=ab/bd
sin(43°)=18/bd
bd=18/0.68199
bd=26.393 miles
As bc>bd
The correct option is Plane A because it was 27.43 miles away ....
The measure of x in both parts is: 120°
Step-by-step explanation:
Part A:
We can clearly see that the figure in part a has six equal sides. So the given figure is a hexagon.
A hexagon has six equal sides in six equal interior angles.
Sum of interior angles of hexagon is 720°
So,
Part B:
The figure is a Dodecagon with 12 sides.
The Dodecagon has 12 equal sides and angles.
The sum of internal angles of Dodecagon is 1440°
So,
The measure of x in both parts is: 120°
