Answer:

The answer to your question is: x = 45°

Step-by-step explanation:

We must know that the sum of the internal angles in a triangles equals 180°.

Then                ∠A + ∠B + ∠C = 180°

Substitution

                       55° + 80° + ∠C = 180°

                       135° + ∠C = 180°                        Simplification

                       ∠C = 180 - 135

                       ∠C = 45°

                       ∠C = x

                      x = 45°                                       Result

BaLLatris [955]

Answer:

n = 95/14, or 6 11/14

Step-by-step explanation:

Let the number be n.  Then:

n - 1 2/7 = 5 1/2.

Multiplying each term by the LCD (which is 14), we get:

14n - 18 = 77

Then 14n = 95  

and so the desired result is n = 95/14, or 6 11/14

Two towns that are 31.5 km apart are 3 cm apart on a map. what is the scale of the map?
VLD [36.1K]

<u>Answer:</u>

1 cm : 10.5 km

<u>Step-by-step explanation:</u>

We are given that two towns are 31.5 km in real and are 3 cm apart on a map and we are to find the scale of the map.

For this, we can use the ratio method.

\frac { 3 cm } { 1 c m } = \frac { 3 1 . 5 k m } { x }

x = \frac { 3 1 . 5 \times 1 } { 3 }

x = 1 0 . 5

Therefore, the scale of the map would be 1 cm : 10.5 km.
