b) Your sister says that the angles ∠DCA and ∠BCA are supplementary angles. Is she correct? Explain your reasoning. (1 point)
c) Is triangle DCA congruent to triangle BCA? Explain. (2 points)
Answers
Answer:
B) No, supplementary angles are either of two angles whose sum is 180 degrees.
C) Yes, the triangles are congruent because the triangles have exactly the same size and shape
Step-by-step explanation:
B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.
C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.

The product of ages of Hasni and Alia is 32 years. Hasni is 4 years older than Alia. How old are Hasni and Alia?
Answers
This gives us 8 and 4, and since Hasni js 4 years older than Alia, Hasni must be 8 years old and Alia must be 4 years old.
If the product of the ages of Hasni and Alia is 32 years and Hasni is 4 years older than Alia, then Hasni would be 8 years old while Alia would be 4 years old.
How to determine the agesFirst, the question states that the product of the ages of Hasni and Alia is 32 years old. We can represent mathematically in the following way;
ab = 32
Assuming b = a + 4, then we would have;
a(a + 4) = 32 years
a² + 4a = 32 years
a+8)(a - 4) = 32 years
So, the ages are expressed as follows:
x + 8 = 0 or x - 4 = 0
Hasni's age is 8 while Alia's age is 4.

2.) -10.28 in.
3.) 25.7 yd
Step-by-step explanation:
formula is P=1/2(3.14)d+ d
1.) P=1/2x(3.14x22)+22
3.14x22= 69.08
69.08/2= 34.54
34.54+22= 56.54
2.) P=1/2x(3.14x-4)+-4
3.14x-4= -12.56
-12.56/2= -6.28
-6.28+-4= -10.28
3.) P=1/2x(3.14×10)+10
3.14×10= 31.4
31.4/2= 15.7
15.7+10= 25.7

You start at 92°
Every hour you lose 2 degrees for 5 hours

Every triangle has a total of 180 degrees
Answer:
56
Step-by-step explanation:
The angles of a triangle add up to 180 degrees. In this case, we have 2 values.
First, we add the two values that we already have so 91 + 33 = 124
To find the length of the missing angle, we subtract 124 from 180.
180 - 124 = 56
And 56 is the value of x.

In order to calculate the time it took, multiply 6.76 by 26/60. This is due to the formula d=rt. Then add that result to 5∗5.55/10. Then, subtract that result from 11.54.
= 11.54−3.85433333333
=9.53566666667
Now, divide it by the regular speed of 9 km/hr.
= 1.05951851852 hours.
Multiply the decimal part by 60.
=1 hour 3.571 minutes.
Multiply the decimal part again by 60.
=1 hour 3 minutes 34 seconds.

describe a sequence of transformations that maps figure a to figure b
Answers
Answer:
rotate CCW 90°dilate by a factor of 2Step-by-step explanation:
First of all, we need to discover the relation Figure B has to Figure A.
Figure B has dimensions that are twice those of Figure A, so a dilation by a scale factor of 2 will be required. The "points" of figure A are on its "south" side, while those of figure B are on its "east" side. Rotation 90° CCW will be involved.
If we consider just these two transformations, we find that they are sufficient to map A to B without any additional translation. Since both transformations use the origin as a reference, their order does not matter.
__
Rotating figure A by 90° CCW moves the vertex of its "notch" from (2, 2) to (-2, 2). Dilating the rotated fibure by a factor of 2 moves its "notch" vertex to (-4, 4), as shown in Figure B.
A suitable sequence of transformations is ...
Rotation 90° CCWDilation by a factor of 2 about the originThese can be done in either order.
_____
Additional comment
The transformations are ...
(x, y) ⇒ (-y, x) . . . . . . rotation 90° CCW
(x, y) ⇒ (2x, 2y) . . . . dilation by a factor of 2
The composition of these transformations is ...
(x, y) ⇒ (-2y, 2x)
Answer:
dilate by a factor of 2
rotate CCW 90°
