Answer:
I totally get why you are asking , how do I solve this. there is so much implied about this
Step-by-step explanation:
1st you have to recognize that ∠ACB ( in my drawing ) has that same angle as the arc from A to B , so that's implied. next you have to recognize that the triangle formed by ACB with the 124 degree angle at C is an isosceles and therefore has identical angles at A and B so that's 180 = 124 + 2A , so A = 28° and so does B , then , b/c we know that small angle... you also have to know, that the line AC is perpendicular to AD. that they from a right angle and there for... you now know , that ∠BAD is the other part of that 90 or 90= 28 + ∠BAD so ∠BAD = 62°
I went through that kinda fast, there was several "leaps" of using logic to get to the correct answer , using things you know from prior understanding about angles , circles and geometry, you are putting all of the parts together here. :/ kinda daunting in some ways.
Hello,
your answer should be true if you put parenthesis!
=1/2[log base 9(57)-log base9 (74)]
=1/2 log base 9 (57)-1/2 log base 9(74)
-9×36÷-15×4
-324÷60
-5.4
(not sure if this is what you are looking for)
Answer:
The transformation

maps triangle XYZ onto triangle X”Y”Z”.
Step-by-step explanation:
Let us take point Z on the XYZ triangle and see what sequence of transformations we have to apply to map it into the point Z''.
Now Z = (-2, 2) and Z'' = (-7, -1).
The x-coordinate goes from -2 ⇒ -7.
The y-coordinate goes from 2 ⇒ -1.
The x-coordinate is just shifted by -5; thus,
, and the y-coordinate first transforms as
, and is then shifted by 1; thus, it transforms as
.
So we have the full transformation

Answer:
Midpoint( .5,-2.5)
Step-by-step explanation:
To find the midpoint, add the x coordinates and divide by 2 and then add the y coordinates and divide by 2
x: (-1+2)/2 = 1/2=.5
y: (-9+4)/2 = -5/2 = -2.5
Midpoint( .5,-2.5)
