Answer:
Congruent angles and proportional side lengths
Step-by-step explanation:
Answer:
It will increase by 9 units.
Step-by-step explanation:
We can write the lowest number as 10a + (a + 1) and the highest is the reverse which is 10(a + 1) + a.
Subtracting:
10(a + 1) + a - (10a + a +1)
= 10a + 10 + a - 10a - a - 1
= 10a - 10a + a - a + 10 - 1
= 10 - 1
= 9.
Answer:
- Scale factor = 1/2 and x = 18
Step-by-step explanation:
<u>Given:</u>
- ΔABC ~ ΔDEF
- AB = 36. BC = 30
- DE = x, EF = 15
- m∠B = m∠E = 72°
<u>Corresponding sides are:</u>
<u>Corresponding sides have same ratio:</u>
- AB/DE = BC/EF
- 36/x = 30/15
- x = 36/2
- x = 18
<u>The scale factor is:</u>
Answer:
Options B, D and E
Step-by-step explanation:
From the picture attached,
AB and CE are the parallel lines and three lines AD, AC and BE are intersecting these parallel lines.
m∠A = m∠C = 90°
Therefore, AC is perpendicular to the lines AB, CD and CE.
Options B, D and E are the correct options.
Answer:
6x = -29 (Bear in mind I can't see all of the options you can pick from, so this is the closest I can get.)
Step-by-step explanation:
First, write out the equation.
6(8 + x) = 19. x is our unknown, or our variable.
Now, simplify the equation.
6(8 + x) = 19
48+ 6x = 19
Next, isolate the variable (get the variable alone)
48 + 6x = 19
-48 -48
6x = -29.
Finally, solve (Your solution should lay along the lines of the equation directly above this, but if it wants the solution here it is.)
6x = -29
/6 /6
x = -4.8333
