Answer:

20 ,70

Step-by-step explanation:

Complementary angles sum up to 90

2x + 4x + 30 = 90

     6x  + 30 = 90

Subtract 30 from both sides

6x = 90 - 30

6x = 60

x = 60/6

x = 10

2x = 2*10 = 20

4x +30 = 4*10 +30 = 40 +30 = 70

Answer:

20 and 70

Step-by-step explanation:

2x + 4x + 30 =90

6x=90-30

6x=60

x=60/6x

x=10

so, 2x= 20 and 4x=40

20,70

Can someone please please please help.?
Luden [163]

Answer:

<h2>43°</h2>

Step-by-step explanation:

In a cyclic quadrilateral, the sum of two opposite angles are equal.

m<R + m<P = 180°

plugging the values:

3y + 8 + y = 180°

Combine the like terms:

4y + 8 = 180°

Subtract 8 on both sides

4y + 8 - 8 = 180 - 8

Calculate the difference

4y = 172

divide both sides of the equation by 4

4y/4 = 172/4

calculate

y = 43°

Hope this helps...

Rearrange the equation A = xy to solve for x.
mote1985 [20]
X = A/y
You divide the y from both sides
The y on the right cancels
On the left you have A/y = x
