Answer:
Deficit means loss
budget means an estimate of income and expenditure for a set period of time.
Q. 1 Deficit and Budget :
Deficit : An amount by which an amount falls short of the required amount.
Budget : A budget is an estimate of revenue and expenditure over a specified future period.
A budget deficit is the amount by which an individual, business, or government's income fall short of the expectations set forth in its budget over a given time period.
Q. 2 ABCD is a parallelogram. Angle B = 5x + 25 degree and Angle D = 8x - 5 degree. Find x and angle C.
Solution : Here, a/c to question
- ∠ B = 5x + 25 ----{1}
- ∠ D = 8x - 5 ----{2}
Here we know that; the opposite angles of the parallelogram are congruent.
Hence, a/c to figure; ∠ A = ∠ C and ∠B = ∠ D ----{3}
➜ ∠ B = ∠ D
➜ 5x + 25 = 8x - 5
➜ 5x - 8x = - 5 - 25
➜ - 3x = - 30
➜ 3x = 30
➜ x = 30/3
➜ x = 10
Now, put value of x in eq. {1} and eq. {2}
➜ ∠ B = 5x + 25
➜ ∠ B = 5 * 10 + 25
➜ ∠ B = 50 + 25
➜ ∠ B = 75⁰
and
➜ ∠ D = 8x - 5
➜ ∠ D = 8 * 10 - 5
➜ ∠ D = 80 - 5
➜ ∠ D = 75⁰
Parallelograms have angles totalling 360⁰.
Hence,
➜ ∠ A + ∠ B + ∠ C + ∠ D = 360⁰
from {3}
➜ ∠ A + ∠ A + 75⁰ + 75⁰ = 360⁰
➜ 2 * ∠ A + 150⁰ = 360⁰
➜ 2 * ∠ A = 360⁰ - 150⁰
➜ 2 * ∠ A = 210
➜ ∠ A = 210/2
➜ ∠ A = 105⁰
∴ ∠ A = ∠ C = 105⁰
Answer : Hence, the of of x is 10 and the angle C is 105⁰.
{More info : Properties of the parallelogram
- The opposite sides are parallel and congruent
- The opposite angles are congruent
- The consecutive angles are supplementary
- If any one of the angles is a right angle, then all the other angles will be at right angle
- The two diagonals bisect each other
- Each diagonal bisects the parallelogram into two congruent triangles
- The Sum of square of all the sides of parallelogram is equal to the sum of square of its diagonals }
