Answer:
x = 29
Angle A = 46.4°
Angle B = 43.6°
Step-by-step explanation:
Since it is a right angle triangle, we can find x from pythagoras theorem;
x = √(20² + 21²)
x = √(400 + 441)
x = √841
x = 29
Using trigonometric ratios we can find angles A and B.
Opposite is 20
Adjacent is 21
Thus; opp/adj = tan B
20/21 = tan B
B = tan^(-1) 0.9524
B = 43.6°
Sum of angles in a triangle is 180°. Thus;
A = 180 - (90 + 43.6)
A = 46.4°
To find 10% of a number, move the decimal point one place to the left.
$23.47 becomes $2.347
The closest answer is C $3
The strings cost $14. you would take the total cost ($72) and subtract the cost of the book ($16) and you would get $56. you would then divide 56 by the number of book bought (4 in all) and you would get $14.
With this problem, you have to do order of operations.
you do the multiplying first (the part in parenthesis)
(5 x 1/3) - (3 x 2/3)
5/3 - 6/3 = -1/3
C.
Because the given condition required to have a flower garden first and then the probability of having a vegetable garden is calculated.
