Answer:
x = 12
Step-by-step explanation:
(8x - 1) + (3x + 4) + (3x + 9) = 180 degrees
14x + 12
180 - 12 = 168
14x = 168
/14 | /14
x = 12
Top left angle: (8x - 1)
8*12 - 1
96 - 1
= 95
Sorry! gtg I hope this helps!
A = L * W
280 = 14 * A
A = 280 / 14
A = 20
A = 2 tens
Big rectangle: A = 280 + (14 * B)
378 =280 + 14B
14B = 378 - 280
14B = 98
B = 7
So length = 2 tens + 7 = 27
Answer
C. 2 tens + 7 = 27
The length of the actual dinning room is 6 metres.
<h3>How to find the actual length of the dinning room?</h3>
Tanner made a scale drawing of an apartment.
He used the scale 1 millimetre : 2 meters.
In the drawing, the dining room is 3 millimetres long.
Therefore,
1 millimetre = 2 meters
3 millimetres = ? metres
cross multiply
Hence,
length of the actual dinning room = 3 × 2 / 1
length of the actual dinning room = 6 metres
Therefore, the length of the actual dinning room is 6 metres.
