Answer:
Rectangle
Step-by-step explanation:
The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Complex number is in the form z = a + bi, where a, b are real numbers.
Given the complex number z = 1 + 3i
In polar form: r = √(1² + 3²) = 3.16
Ф = tan⁻¹ (3/1) = 71.57⁰
The trigonometric form of the complex number 1 + 3i is 3.16[cos(71.57)° + isin(71.57°)]

Answer:
15/4
Step-by-step explanation:
5 = 5/1
Then you just multiply across, 5*3=15 and 1*4=4 so you get 15/4.
Answer:
A. 21.2
Step-by-step explanation:
Using trigonomteric ratio, Cosine
Cosine B = a/c
But; c = 24
B = 62
Cos 62 = a/24
a = 24 × cos 62
= 11.26
Using Pythagoras theorem we can get b;
since; a² + b² = c²
b² = 24² - 11.26²
= 449
b = √449
= 21.19
≈ 21.2
