Answer:
Step-by-step explanation:
In Δ AFB,
∠AFB + ∠ABF + ∠A = 180 {Angle sum property of triangle}
90 + 48 + ∠1 = 180
138 + ∠1 = 180
∠1 = 180 - 138
∠1 = 42°
FC // ED and FD is transversal
So, ∠CFD ≅∠EDF {Alternate interior angles are congruent}
∠2 = 39°
In ΔFCD,
∠2 + ∠3 + ∠FCD = 180
39 + ∠3 + 90 = 180
129 +∠3 = 180
∠3 = 180- 129
∠3 = 51°

Answer:

Step-by-step explanation:
We are given the following in the question:
Cost of one cupcake = $3.50
Cost of one fruit tart = $3
Total money Harry have = $50
Harry bought 8 cupcakes and
fruit tarts.
We have to write the inequality giving relation between the total number of cupcakes and fruit tarts Harry can buy the amount of money he has.
Total cost of purchase =
= Total cost of cupcakes + Total cost of fruit tarts

Now, this total cost of Harry's purchase should be less than than equal to $50.

is the required linear inequality.
The third side is 10 cm long. Triangles have two identical sides, and one different.
