Answer:
-4-i2
The absolute value is the Square root of the real and Imaginary Parts of the Complex No
= √(-4)²+(-2)²
=√16+4
=√20
=2√5
Answer:
C = 25
a = 10.72
b = 11.83
Step-by-step explanation:
The easiest thing to solve for right now is C- all angles in a triangle add up to 180 degrees. So we can subtract 65 and 90 from 180 to get the measure of angle C, 25 degrees.
Then we can use trigonometric functions: SOH CAH TOA
sinC = opposite / hypotenuse
sin25 = 5 /hyp
5/sin25 = hyp
hyp (aka b) = 11.83
cosC = adjacent / hypotenus
cos25 = a/11.83
11.83*cos25 = a
a = 10.72
C = 25
a = 10.72
b = 11.83
Am I supposed to find the number for the question mark if so then it’s 18
