137 degreessssss !!!!!!!!!!
Answer:
Answer down below!
Step-by-step explanation:
1) 10
2) 4
3) 6
----------------
1 ) we know that perimeter = all the sides combined.
- (44 is the given perim.; so therefore if 12x2+10x2=44, 20 is the missing width.
2 ) we know that area = lw.
- 44 is the given area, so therefore if 10x4=40, 4 is the base.
3 ) we know that area = lw.
we need to find the area of the square. 3 x 2 = 6. 6 is the area of the missing square or the part that needs to be covered.
Answer: 21 degrees
Step-by-step explanation:
In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:
= 28° - 31°
= -3°
Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:
= -3° - 6°
= -9°
Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:
= -9° + 30°
= 21°
Given the sets A = {-4, -1, 3, 5, 9} and B = {-2, -1, 0, 1, 2, 3}, the set AUB (u is upside down) is given by:
ki77a [65]
The upside down U is the symbol for the intersection of sets. The intersection of two sets is the set that contains the elements that are common to both sets. Which elements are both in set A and in set B?
Answer: {-1, 3}
Answer:
The correct option is;
r = √(x² + y²)
θ = tan⁻¹(y/x)
Step-by-step explanation:
The rectangular coordinate of a complex number on the complex plane is given as (x, y)
Given that the complex number is represented by a point on the plane, we have;
The distance, r, of the point from the origin, (0, 0) is r = √(x² + y²)
The direction, θ, by which we rotate to be in line with the point on the complex number is given by tan⁻¹(y/x)
