Step-by-step explanation:
since it's negative it'll give you a different answer:)
Answer:
True
m∠T = 40.4°
Step-by-step explanation:
We know all the sides of the triangle but we do not know any of its angles.
To find out if the angle T = 40.4 ° we use the cosine theorem.
According to the cosine theorem:
Where is the angle between a and b.
In this case:
Then we clear α from the formula and verify that it is equal to 40.4 °
Answer:
2
Step-by-step explanation:
find the greatest common factor, and then it is x^2(x+2) (x+7)
Answer:
X'() Y'() Z'()
Plot accordingly
Step-by-step explanation:
Dilatation could be either stretching (bigger) or shrinking (smaller).
To find the dilated values of a point, multiply the x and y values by the scale factor. (In this case it is 1/4).
It's essentially the same principle of what you did in the first question.
