Answer:

so the labelled angles are 30 and 90, but it only shows one 90. In fact there are 4 angles of 90. The marked 90 then the vertical angle and the complementary angles. All triangles equal 180 so the given 30 and 90 are taken from the 180.

180 -30-90= 60

But y is the opposite of the 30 which makes y=30

so that leaves x = 60

y=30 and x=60

ankoles [38]

Answer:

The price per CD that Drew bought=$11

Step-by-step explanation:

Margie's total cost can be expressed as;

C=(p×n)+t

where;

C=total cost

p=price per unit of CD

n=number of CD bought

t=tax on purchase

In our case;

C=$61

p=unknown

n=5

t=$6

replacing;

61=(5×p)+6

5 p+6=61

5 p=61-6

5 p=55

p=55/5

p=11

The price per CD that Drew bought=$11

Solve for x in both!!!!!

zvonat [6]

Answer:

$- 2(x - 2) - 4x = 3(x + 1) - 9x \\ - 2x + 4 - 4x = 3x + 3 - 9x \\ 9x - 3x - 2x - 4x = 3 - 4 \\ 9x - 9x = - 1 \\ 0x = - 1 \\ 0 = - 1$

So ; No solution

___o___o____

$5(x + 2) - 3 = 3x - 8x + 7 \\ 5x + 10 - 3 = - 5x + 7 \\ 5x + 7 = - 5x + 7 \\ 5x + 5x = 7 - 7 \\ 10x = 0 \\ \\ x = \frac{0}{10} \\ \\ x = 0$

I hope I helped you^_^

How many triangles can be constructed with angles measuring 80 degrees , 80 degrees and 40 degrees

daser333 [38]

Answer:

None

Step-by-step explanation:

The angles inside a triangle add to 180. If the angles are 80, 80 and 40, then they must add to 180 to form a triangle.

80+80+40 = 200

This can't be a triangle.
