1. how to find angle between two lines in which one is perpendicular to x axis
To find angle between two lines in which one is perpendicular to x axis
Let the two straight lines be AT1 and AT2 which meet at x-axis at T1 and T2 points respectively.
Let the equations of the two lines AT1 and AT2 be
y = m1x + c1 and y2 = m2x + c2 (1)
Hence tan AT1X = m1 and tan AT2X = m2
Now ∠T1AT2 = ∠AT1X - ∠AT2X
Hence tan T1AT2 = tan [AT1X - AT2X]
= tan AT1X - tan AT2X/ 1+ tan AT1X.tan AT2X = m1 - m2/ 1 + m1.m2
Hence the required angle = ∠T1AT2
= tan -1 m1-m2/1+m1.m2
If equation (2) is a positive quantity then it is the tangent of the acute angle between the two lines, if (2) is a negative quantity then it is the tangent of the obtuse angle.

3. Given a triangle ABC. Angle A is 50 degrees. Angle B is 23 degrees greater than angle C. Calculate angle B and C
Given :
∠A = 50°
∠B = 23° + ∠C
Question :
∠B = ?
∠C = ?
Answer :
In Triangle we know that the sum of internal angles of triangle is equal to 180°.
∠A + ∠B +∠C = 180°
50° + 23° +∠C +∠C = 180°
73° + 2 ∠C = 180°
2∠C = 180° - 73°
2∠C = 107°
∠C = 107° ÷ 2
∠C = 53.5°
∠B = 23° + 53.5°
∠B = 76.5°
4. Linear equation for a line runs through (-2,3) and perpendicular to y= 3x +5
Parallel gradient (m1) = 3
Perpendicular gradient (m2) = - 1/3
Linear equation formula :
(y - b) = m2(x - a)
(y - 3) = (-1/3)(x + 2)
3y - 9 = -x - 2
3y = -x + 7
x + 3y - 7 = 0
m = 3 because of perpendicular so m will be - 1/3
The linier equation is:
y - 3 = -(1/3)( x - -2)
3y - 9 = 1x + 2
3y - x - 9 - 2 = 0
3y - x -11 = 0

8. The Lines Meet At the Point O. ANGLE AOC = 210° and ANGLE BOC = 254°. Find ANGLE AOB
See the question :
"The Lines Meet At the Point O. angle AOC = 220° and angle BOC = 254°. Find angle AOB = ... ?"
Discussion :
The first step. we have to know one circle. we subtract one circle with the angle BOC. and the result is the remaining angle
360° – 254° = 106°
second step. we subtract the angle of AOC with the remaining angle.
210° – 106° = 104°
So, angle AOB is a 104°
The model, we can see in the appendix below

9. When there is triangle ABC, the angle A is 55 and angle C is 60. What is the size of angle B? 75'65'55'85'
Jawaban:
triangle is a 180° shape
So if we use that assumption then
180 - 55 - 60 = 65°
So angle B's size is 65°
THE ANSWER IS B
