Answer:
The answer is 74.24 square millimeters
Answer:
Hence third choice RQ, RP, PQ is correct.
Step-by-step explanation:
We know that if A, B, C are the angles of the triangle and if ∠A > ∠B
a>b {Where “a” is side created by angle A and “b” is side created by angle B }.
We will use same property to decide which side is bigger.
In triangle PRQ,
∠P = 30 degree
∠R = 85 degree
then ∠P + ∠R + ∠Q = 180 {since sum of all three angle of triangle is 180 degree}
30 + 85 + ∠Q = 180
115 + ∠Q = 180
∠Q = 180 - 115
∠Q = 65
Now we know measure of all angles so we can do comparison using above property.
Smallest angle is ∠P so side RQ will be smallest.
Largest angle is ∠R so side PQ will be largest.
Hence we get RQ < RP < PQ.
Hence third choice RQ, RP, PQ is correct.
Answer:
The magnitude of the vertical component of vector u is
The magnitude of the horizontal component of vector u is
Step-by-step explanation:
A vector quantity has, a magnitude and a direction
The horizontal component of vector is ║u║ cos α
The vertical component of vector is ║u║ sin α
∵ The magnitude of vector u is 12 ft
∵ The measure of angle α is 135°
- Substitute the magnitude and the angle in the rule of
each component
∴ = 12 cos(135)
∴ = 12 sin(135)
∵ cos(135) =
∴ = 12 ( )
∴ =
- The magnitude of a number means the number without its sign
∴ The magnitude of the horizontal component of vector u is
∵ sin(135) =
∴ = 12 ( )
∴ =
∴ The magnitude of the vertical component of vector u is
Answer:
true
Step-by-step explanation:
its like a bar graph but joint. theres no space between two consecutive bars
Answer:
There is no real number root
Step-by-step explanation:
There is no real number root because there is a negative number inside the root.
