Let us start with the unknown. Let us give one of the base angles the
value of x. The other base angle is also x since both the base angles in
an isosceles triangle will be equal. The remaining angle is 40 more
than three times one of the base angles.It is 3x + 40. Here we get the
equation
x+x+3x+40=180
5x + 40 = 180
5x = 180 - 40 = 140
Therefore x = 140/5 = 28
So the angles are 28, 28 and 124.
The third angle is 3 times 28 + 40 = 84 + 40 = 124.
For this case we must factor the following expression:

We rewrite the middle term as a sum of two terms whose product is

And whose sum is

These numbers are:
-5 and -3
So:

We factor the maximum common denominator of each group:
We take common factor

Answer:

Answer:
The mass of a longhorn cow.
Step-by-step explanation:
Kilograms will measure mass, not length, so we are left between two options. Kilograms would be used for heavier objects, so between a paper clip (which would be likely measured in grams,) and the longhorn, the cow would be what you would measure in kilograms.
Answer:
$3.17
Step-by-step explanation:
Take the $12.69 and divide it by the 4 kilograms and you get 3.17. (This is rounded)
