Answer:
m∠A=52°
Step-by-step explanation:
Because of the exterior angle theorem, m∠A+m∠B=105° (The exterior angle)
We then end up with an equation like this...
m∠A+m∠B=105°
Then, you do the substitution...
x+53°=105°
Subtract 53 from both sides...
x=105°-53°
x=52°
Answer:
Scale factor of 2
Explanation:
I compared the lengths of AC to DF. AC is one unit long, whereas DF is two units long, so DF is dilated by a scale factor of 2.
Answer: 25 square units
Step-by-step explanation:
We mark the points, A(2,0), B(7,0), C(10,3), D (5,3). on a graph and then joined them to make parallelogram ABCD as provided in the attachment.
Area of parallelogram = Base x corresponding height
From the figure, base AB = 7 - 2 units = 5 units
corresponding height: h= 5 units
Now , Area of parallelogram ABCD = base AB x corresponding height
= 5 x 5 square units
= 25 square units
Hence, the area of parallelogram ABCD is 25 square units .
Answer:
The answer is <u><em>20,880</em></u>
Step-by-step explanation:
This won't be a very long explanation. What I did was add 18,000 plus 16% and I got <u><em>20,880</em></u>.
Hope this helps!

Answer:
Yea that problem is a bit confusing,
2y should be double of what y is, which is 4x+5
Then 2y says 8x+15, when it should be 8x+10.
I feel bad cause I am sure the teacher is wrong on this, he/she had probably made a typo, or you made a typo, but that's ok! We all make typos!
The teacher would be extra rude if they marked you wrong on this, cause the question itself is not written "properly"
