Answer:

m<1 = 45°  

m<2 = 76°

m<3 = 80°

Step-by-step explanation:

<u>Points to remember</u>

1). Vertically opposite angles are equal

2). Sum of angles of a triangles is 180°

<u>To find the measures of given angles</u>

From the figure we get,

m<1 = 45°   [Vertically opposite angles]

By using angle sum property <2 + 59 + 45 = 180

m<2 = 180 - 104

m<2 = 76°

Also m<1 + m<3 + 55 = 180

m<3 = 180 - (m<1 + 55)

 = 180 - (45 + 55)

 = 180 - 100

m<3 = 80°

Solve the system of equations.<br><br> 14x + y = −4<br><br> y = 3x^2 − 11x − 4
sveta [45]
You can use substitution here. First, get y alone:

14x + y = -4
subtract 14x from each side
y = -4 - 14x

Then, plug y into the second equation

-4 - 14x = 3x² - 11x - 4
 then solve from there

Hope this helps :)

Fill 350 milliliter bottles from a 30 liter drum how many bottles
Mama L [17]

Answer:

  85

Step-by-step explanation:

0.350 L × n = 30 L . . . . . where n is the number of bottles.

Divide by 0.350:

  n = (30 L)/(0.350 L) ≈ 85.7

85 bottles can be filled, and one can be partially filled.

_____

Of course, you know the SI prefix milli- means 1/1000, so 350 mL = 350/1000 L = 0.350 L. When you do the division indicated above, ...

  (30 L)/(0.350 L)

the units of liters cancel, and you are left with the number of bottles.
