AB = AC

Therefore, ∠B =∠C ( Angles Opposite to equal sides are equal )

∠A+∠B+∠C = 180° (Angle Sum Property)

or, ∠A+50°+50° = 180°

or, ∠A+100° = 180°

or, ∠A = 180°-100°

or, ∠A=80°

Therefore, ∠A=80°

This ΔABC is an isosceles triangle. In this kind of triangle, two of the sides are equal.
So if AB=AC,
Then vertex= angle A and
Base angles= angle B and angle C which are equal.
Let the base angles angle B and angle C be x.
Since the sum of the angles of a triangle=180°,
Therefore,
angle A + angle B + angle C = 180°
= 120° + x+x= 180°
= 120° + 2x= 180°
= 2x = 180°-120°
= 2x = 60°
= x = 60°/2 =30°
Therefore,
Angle A= 120°
Angle B= 30°
Angle C= 30°.

(1),2x+y =7 2x+y=7 2×0+y=7 0+y=?

Yogita Ingle 4 years, 2 months ago

(a)2x + y = 7......(1)

On putting x=0 in equation 1

2x+y=7

2×0+y=7

0+y=7

y=7

So( 0, 7) is a solution of given equation.

let y=0

2x+y=7

2x+0=7

2x=7

X= 7/2

So(7/2,0) is a solution of given equation.

let x = 1

2x+y=7

2×1+y=7

2+y=7

Y= 7-2

Y=5

(1,5) is the solution.

let x = 2

2x+y=7

2×2+y=7

4+y=7

Y= 7-4

Y= 3

The solution is (2,3)

Hence, 4 out of the infinitely many solutions of the given equation are(0,7), (7/2,0),(1,5),(2,3)

(b) πx + y = 9

let x = 0

πx + y = 9

π×0+y =9

0+y= 9

Y=9

 (0,9) is the solution.

Let y = 0

πx + y = 9

πx+0=9

πx=9

x= 9/π

 (9/π,0) is the solution.

Let x = 1

πx + y = 9

π×1+y=9

π+y=9

Y= 9-π

(1,9-π) is the solution.

Let x = -1

πx + y = 9

π×-1+y=9

-π+y=9

Y= 9+π

 (-1,9+π) is the solution.

Hence, 4 out of the infinitely many solutions of the given equation are(0,9), (9/π,0),(1,9-π),(-1,9+π)

(c) x= 4y

Let x = 0

X=4y

0=4y

Y=0/4=0

Y=0

(0,0) is the solution.

Let x= 1

X=4y

1=4y

Y= 1/4

(1,1/4) is the solution.

Let y = 1

X=4y

X=4×1

X=4

(4,1) is the solution.

Let x = 2

X=4y

2=4y

Y=2/4

Y=1/2

(2,1/2) is the solution.

Hence, 4 out of the infinitely many solutions of the given equation are(0,0), (1,1/4),(4,1),(2,1/2)

P(x) -X³+2x²-7x+6 is an example of polynomial because the power of x variable are 3 , 2 , 1 and 0 which are positive and not in fraction. Similarly √2 x +3x⁴ is also polynomial beacaues power of variable X are 1 and 4 which are positive and not in fraction.

Solution: To draw a graph of linear equations in two variables, let us find out the points to plot. To find out the points, we have to find the values which x and y can have, satisfying the equation. Here, y + x = 5 Substituting the values for x, When x = 0, y + x = 5 = y + 0 = 5 = y = 5 When x = 5, y + x = 5 = y + 5 = 5 = y = 5 – 5 = y = 0 x y 0 4 5 0 ∴, The points to be plotted are (0, 4) and (5,0). (Note-Draw the graph by using the coordinates.)
