Answer:
−5+11i
Step-by-step explanation:
(3+6i)−(8−5i)
Subtract 8−5i from 3+6i by subtracting the corresponding real and imaginary parts.
3−8+(6−(−5))i
Subtract 8 from 3. Subtract −5 from 6.
−5+11i
Answer:
x = 97
y = 83
Step-by-step explanation:
y = 83 (being the vertically opposite angle )
y + x = 180 (being co-interior angle)
or,
83 + x = 180
or,
x = 180 - 83
.•. x = 97
Answer:
2*√2
Step-by-step explanation:
You need to use the trigonometrical function of angle (You should use the side sqrt2 and x to find the x). Take any acute angle (for example, 60 degrees)
The cos of this angle is equal to the ratio of adjoined leg (sqrt2) to the hypotenude (the side opposite to right angle, it is x)
cos60degrees= sqrt2/ x
1/2= sqrt2/x
x= 2*sqrt2= 2*√2
The ratio is 96:3 or 96/3 all you have to do is just divide but not solve the question. It's like writing an expression.
