How to find an unknown angle in a quadrilateral

Mathematics
1 answer:
cricket20 [7]3 years ago

Subtract the sum of the angles from 180 degrees to get the missing angle. For example if a triangle in a quadrilateral had the angles of 30 and 50 degrees, you would have a third angle equal to 100 degrees (180 - 80 = 100).

In the figure below, Angle ADC measures 50 degrees, and Angle BAC measures 90 degrees. What is the measure of Angle BAD?
juin [17]
Well I do not see the figure but I will assume it is a triangle. there are 3 angles in a triangle. Those 3 angles add up to 180. Since we know this, you can use the equation
angle1 + angle2 + angle3 = 180

we have 2 of the angles so with a little algebra we can solve for the last angle like this
180 - angle1 - angle2 = angle3

plug in 2 angles
180 - 50 - 90 = angle3

So answer is
angle3 = 40 degrees

-1/2x + 1/8 = -1/3x - i/4
brilliants [131]

Answer:

x= 4/9

Step-by-step explanation:

-1/(2x) + 1/8 = -1/(3x) - 1/4

-1/(2x)+1(3x)= - 1/4 -1/8

-3/(6x)+2(6x) = -2/8 -1/8

- 1/(6x) = - 3/8

-1*8 = -3*6x

8=18x

x= 8/18= 4/9

Check:

-1/(2*4/9) + 1/8 = -1/(3*4/9) - 1/4

- 1(8/9) + 1/8 = - 1/(4/3)-1/4

-9/8+1/8 = - 3/4-1/4

-1 = -1
