Answer:
120 cm^2
Step-by-step explanation:
area of a rhombus is pq/2
that means that the product of the two diagonals divided by 2 is the area of the rhombus.
so that means one diagonal is 24 and one is 10, (we are given what half of both diagonals are so just multiply by 2)
now put it in the formula
24x10 = 240
now divide by 2
240/2 = 120

So x should be equal to -2 when you equal them to each other.
The result of the decrease of the number 14.4 by 0.2 of it is of 14.2.
<h3>What does it mean to decrease a number a by b of it?</h3>
The equivalent operation is the subtraction of a by b.
In this problem, we want to decrease the number 14.4 by 0.2 of it, hence the operation is:
14.4 - 0.2 = 14.2.

Answer:
•cos(s+t) = cos(s)cos(t) - sin(s)sin(t) = (-⅖).(-⅗) - (√21 /5).(⅘) = +6/25 - 4√21 /25 = (6-4√21)/25
•cos(s-t) = cos(s)cos(t) + sin(s)sin(t) = (-⅖).(-⅗) + (√21 /5).(⅘) = +6/25 + 4√21 /25 = (6+4√21)/25
cos(t) = ±√(1 - sin²(t)) → -√(1 - sin²(t)) = -√(1 - (⅘)²) = -⅗
sin(s) = ±√(1 - cos²(s)) → +√(1- cos²(s)) = +√(1 - (-⅖)²) = √21 /5
