Get the app called Photomath. It should help with this:)
Answer:
B) 421
Step-by-step explanation:
√2 + √-18
√2 + √9·-2
√2 + 3√-2
(3 +1 )(√2 ·√-2) = 2i
4 · 2i
17. 5/4.5 = apx. 3.89
Hope this helps!
2/5 divide -3/10 can be rewritten as 2/5 * - 10/3. Which is -20/15 = -4/3 = -1 1/3
Answer:
Angle = 135°
Supplement of the Angle = 45°
Step-by-step explanation:
The complement of an angle, say "x", would be 90 minus that angle:
90 - x
The supplement of an angle, say "y", would be 180 minus that angle:
180 - y
Since we have 1 angle, let it be "x", and that angle is 3 TIMES the SUPPLEMENT of that angle, we can write:
x = 3(180 - x)
Now, we solve for the angle x:

So, the angle is 135°
The supplement of the angle is 180 - 135 = 45°
