In ΔXYZ, side y = 5 cm, side z = 6 cm, and X = 40°. Find the area of ΔXYZ.

A) 7.5 cm2

B) 9.6 cm2

C) 15.0 cm2

D) 19.3 cm2

The Required area of Δ is .

Step-by-step explanation:

Diagram of given scenario is shown below.

Given that,

, and °

To find : The area of Δ .

So, from the question

Area of triangle when two sides and one angle (between two known sides) are given   , where is the given angle.

Substituting the given values in above to find area of Δ we get,

Therefore, The Required area of Δ is .

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
