Right triangle ABC and right triangle ACD overlap as shown below. Angle DAC measures 20 degrees and angel BCA measures 30 degree
alexdok [17]

The image of the question is attached below.

Given:

m∠DAC = 20° and m∠BCA = 30°

m∠ABC = 90° and m∠CDA = 90°

To find:

The value of x and y.

Solution:

In right triangle ABC,

m∠BAC = x° + 20°

Sum of the interior angles of a triangle = 180°

m∠BAC +m∠ABC + m∠BCA = 180°

x° + 20° + 90° + 30° = 180°

x° + 140° = 180°

Subtract 140° from both sides.

x° + 140° - 140° = 180° - 140°

x° = 40°

In right triangle ADC,

m∠ACD = y° + 30°

Sum of the interior angles of a triangle = 180°

m∠ACD +m∠CDA + m∠DAC = 180°

y° + 30° + 90° + 20° = 180°

y° + 140° = 180°

Subtract 140° from both sides.

y° + 140° - 140° = 180° - 140°

y° = 40°

The value of x is 40 and y is 40.

Please please please I'm begging you help me find the y intercept for these I will give brainliest
konstantin123 [22]

Answer:

1. (2+2)/(-3+4)= 4/1= 4

y + 2 = 4(x + 4)

y + 2 = 4x + 16

y = 4x + 14 y-intercept:(0,14)

2. (0+5)/(-1+2)= 5/1= 5

y + 5 = 5(x + 1)

y + 5 = 5x + 5

y = 5x

y-intercept (0,0)

3. (-1+1)/(-5-3)= 0/-8= 0

y + 1 = 0(x - 3)

y + 1 = 0

y= -1
