Answer:
Step-by-step explanation:
Let the first angle = x
Let the second angle = y
They are complementary so
x + y = 90
x = y + 30
Substitute for x
y + 30 + y = 90
2y + 30 = 90 Subtract 30 from each side
2y = 90 - 30
2y = 60 Divide by 2
2y/2 = 60/2
y = 30
x = y + 30
x = 30 + 30
x = 60
Answers:
<h2>(7, 9), (13, 0), & (15, -4)</h2>
Step-by-step explanation:
1st Pair
X 2 + 5 = 7
Y -3 - -12 = 9
<em>First transformation new coordinates: (7, 9)</em>
2nd Pair
X 8 + 5 = 13
Y -12 - -12 = 0
<em>Second transformation new coordinates: (13, 0)</em>
3rd Pair
X 10 + 5 = 15
Y -16 - -12 = -4
<em>Third transformation new coordinates: (15, -4)</em>
<em>PLEASE MARK BRAINLIEST</em>
If you distribute -4 through (5k-7), it equals -20k + 28. Then put on the other -2k on that side of the equals sign and you should have -22k + 28 = -2(9k+5) Then you need to distribute -2 through (9k+5) which equals -18k - 10. You then should have -22k+28=-18k-10. Add 22k to both sides to cancel it out, then you should have 28=4k-10. Add 10 to both sides to get the 4k by itself, which will be 38=4k, then divide both sides by 4 to get k by itself. 38/4 = 19/2. k = 19/2
Hey there Nc085601pmzc,
Answer:
Perimeter = Length + Breadth + Length + Breadth
= 50 + 25 + 50 + 25
= 150 cm
Hope this helps :D
