Find mZADC. (8x-45)° ETJ B D (7x-45)° A

Mathematics
1 answer:
fgiga [73]1 year ago
8 0

Answer:

= 39°

Step-by-step explanation:

angle BDA = 90°

but angle BDA can also be written as Angle BDA + angle CDA

thus we compute this as

8x-45 + 7x -45= 90

15x -90 = 90

15x = 180

X = 12 angle ADC is therefore= 7x 12 -45

= 39°

The exterior angles of a pentagon are (m+5)°, (2m+3)°, (3m+2)°, (4m+1)° and (5m+4)° respectively. Find the measure of each angle
olga nikolaevna [1]

Answer:

Step-by-step explanation:

Sum of exterior angles of any polygon =360°

Sum of exterior angles of polygon = 360°

m + 5  + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360

m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4  = 360  {Combine like terms}

15m + 15 = 360 {Subtract 15 from both sides}

        15m = 360 - 15

        15m = 345 {Divide both sides by 15}

           m = 345/15

m = 23

m + 5 = 23 + 5 = 28°

2m + 3 = 2*23 + 3 = 46 + 3 = 49°

3m + 2 = 3*23 + 2 = 69 + 2 = 71°

4m + 1 = 4*23 + 1 = 92 + 1 = 93°

5m + 4 = 5*23 + 4 = 115 + 4 = 119°

Find the x-intercept of 2x+2y=2
Nana76 [90]

Answer:

x-intercept: <u>(1,0)</u>

y-intercept: <u>(0,1)</u>

Step-by-step explanation:

Given: Find the x and y intercepts of 2x + 2y = 2

<h2><u>X-intercept</u></h2>

To solve for a x - intercept we have to substitue 0 in for y and solve for x

Lets do it:

2x + 2(0) = 2

2x + 0 = 2

2x = 2

x = 1

Therefore, this means that when y = 0, x = 1 or (1,0)

<h2><u>Y-intercept</u></h2>

To solve for a y - intercept we have to substitue 0 in for x and solve for y

Lets do it:

2(0) + 2y = 2

0 + 2y = 2

2y = 2

y = 1

Therefore, this means that when x = 0, y = 1 or (0,1)
