Answer:
40
Step-by-step explanation:
-1 × 5 = -5
-5 × 2 = -10
-10 × -4 = 40
Answer:
Step-by-step explanation:
Let the scale factor is k.
<u>Then the transformation is:</u>
<u>We have:</u>
<u>The scale factor is k = 12, find the value of a:</u>
- 3a² = 12
- a² = 4
- a = √4
- a = ± 2
Answer:
The answer would still be: K=nm

Hello from MrBillDoesMath!
Answer:
75
Discussion:
A plane triangle has 180 degrees. Using this in the diagram gives
x + 81 + angle BAC = 180 (***)
(The diagram is a bit fuzzy but I think the above numbers are accurate)
The diagram also shows that (156 + angle BAC )= 180 as a straight line has 180 degrees. So
angle BAC = 180 - 156 = 24
Substituting this in (***) above gives
x + 81 + 24 = 180 =>
x + 105 = 180 => (as 81 + 24 = 105)
x = 180 107 = 75
Check: Does
x + 81 + angle BAC = 180 ?
75 + 81 + 24 = 180. Yes
Thank you,
