Solve for x in the diagram Please.

5

Step-by-step explanation:

8x + 50 = 90

8x + (50-50) = 90-50

8x = 40

8x/8 = 40/8

X = 5

Hope this helps!

x = 5°

Step-by-step explanation:

Start off with 8x° + 50° = 90° because it shows that that is a right angle

Subtract 50° from both sides

8x° = 40°

Divide both sides by 8 to get x alone

x° = 5°

Check:

8(5)° + 50° = 90°

40° + 50° = 90°

90° = 90°

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
