Answer:
B = 43°
a = 44.7
c = 53.3
Step-by-step explanation:
✔️B = 180° - (90° + 47°) (sum of interior angles of a ∆)
B = 180 - 137
B = 43°
✔️Use trigonometric ratio formula to find a:
reference angle = 47°
Opposite = a
Adjacent = 29
Thus,
tan 47 = a/29
Multiply both sides by 29
29*tan 57 = a
44.7 = a
a = 44.7 (nearest tenth)
✔️Use trigonometric ratio formula to find a:
reference angle = 47°
Opposite = a = 44.7
Hypotenuse = c
Thus,
Sin 47 = 44.7/c
Multiply both sides by c
c*sin 57 = 44.7
Divide both sides by sin 57
c = 44.7/sin 57
c = 53.3 (nearest tenth)

John is going camping, and he needs to buy a tent. The outdoor store has one that cost $90, but it's on sale for 25% off. What is the sale price?
A.$22.50
B.$65.00
C.$67.50
D.$112.50
Answers
Answer:
A
Step-by-step explanation:
Okay so, im not the best at explaining, but so we have a percentage. its 25%. you want to take the 25% and put it over 100 because a percentage is a number or ratio expressed as a fraction of 100. so it will be written as 25%/100
divide 25 by 100 and you get 0.25, correct? so that's one step further towards the answer.
then we write x/90 because we don't know (well we do) what we're gonna put. but, we're gonna multiply 0.25 by 90 and we get 22.5, which is equivalent to 22.50.
the equation of a circle whose center is (-5, 3) and whose radius is 6?
Answers
Answer:
Center:(-5,3)
The center of a circle is a point from which all points on a circle are the same distance.
Radius:6
The radius of a circle is the length of a line segment from its center to its perimeter.
The radius is typically denoted as "r" or "R".
Diameter:12
The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.
Circumference or (or Permieter) = 2*π*R = 2*3.14*6 = 37.6991118430775
The circumference of a circle is the distance around it.
Area:113.097335529233
Area of a Circle is the amount of space occupied by the circle.The area of a circle is p times the radius squared, which is written: A = π*R2.

Where do the lines y = 3x + 5 and y = -2x + 10 intersect?
Answers
9514 1404 393
Answer:
(x, y) = (1, 8)
Step-by-step explanation:
A graphing calculator quickly tells you the point of intersection.
__
You can equate the y-values and solve for x.
3x +5 = -2x +10
5x = 5 . . . . . . . . . add 2x-5
x = 1 . . . . . . . divide by 5
3·1 +5 = y = 8 . . . . substitute for x in the first equation
The point of intersection is (x, y) = (1, 8).
