the answer would be x=-19.25
There's no such thing as the "length"of an angle.
But we know what you're getting at.
You have said that the angles are complementary. If two angles are
complementary, then their sum is 90 degrees, so we can take your
two angles and write:
<u>x</u> (one angle) plus <u>(2x + 12)</u> (the other one) <u>= 90 degrees
</u><u /> x + 2x + 12 = 90<u>
</u>Subtract 12 from each side: x + 2x = 78
Add the x's on the left side: 3x = 78
Divide each side by 3 : x = 26 degrees
One angle is 'x' = <em>26 degrees</em>
The other one is (2x + 12) = 52+12 = <em>64 degrees</em>
For this problem, just divide 1000 by 5.81 and the answer will be 172.12
Answer:
or 
Step-by-step explanation:
First add 1/5 from both sides to get 2/3x > 6/5. This can then be simplified to x > 18/10. 18/10 is the same as 9/5. And 9/5 is also 1 4/5.
Hope it helps!
Actually Welcome to the Concept of the Congruency.
Q-4 answer is SAS, since alternate angles are equal.
