Gabrielle angles her pool cue against the edge of her pool table, as shown below. What is the measure of angle a and angle b
Answers
The relationship between angle A and angle B is supplementary angles.
∠A = 2(5) + 40 = 50 degrees
∠B = 5 + 125 = 130 degrees
What are supplementary angles?Supplementary angles are angles that sum up to 180 degrees. The sum of the two angles for a supplementary angles is 180 degrees .
Therefore, the relationship between angle A and angle B is supplementary angles.
Therefore,
∠A + ∠B = 180 degrees
∠A = 2x + 40
∠B = x + 125
2x + 40 + x + 125 = 180
2x + x + 40 + 125 = 180
3x + 165 = 180
3x = 180 - 165
3x = 15
x = 15 / 3
x = 5
Therefore,
∠A = 2(5) + 40 = 50 degrees
∠B = 5 + 125 = 130 degrees

find the speed and direction of a plane with a velocity of 〈5,-12〉.
Answers
Answer:
Below in bold.
Step-by-step explanation:
Speed = √(5^2 + (-12)^2)
= √169
= 13,
Direction = arctan (5/-12)
= -22.61 degrees ( its in the 4th quadrant)
So we can write the direction as 90 + 22.61
= 112.61 degrees.

Mia has two cylindrical bird feeders. Her red bird feeder has a diameter of 10 inches and is 8.3 inches tall. What is the volume of the red bird feeder?
Answers
The volume of the red bird feeder will be equal to V=651.88 cubic inches
What is volume?Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length,width and height of the cube or Cuboid.
It is given that:-
Diameter = 10 inches
Height = 8.3 inches
Volume=?
Since the feeder is cylindrical so the volume will be calculated as:-
[tex]\rm Volume=\dfrac{\pi }{4}d^2H\\\\\\Volume=\dfrac{\pi }{4}(10)^2(8.3)\\\\\[/tex]
V=651.88 cubic inches
Hence volume of the red bird feeder will be equal to V=651.88 cubic inches

First subtract 2 on both sides, which results in
-4x>24
Now, divide by -4 on both sides:
x<-6
The inequality sign changed because we divided both sides by a negative number.
So the values of x less than -6 will make this inequality true (will satisfy the inequality).
