Please explain the steps and how I can find the values!!
Xelga [282]

Answer:

a = 4.949

b = 4.949

c = 7

Step-by-step explanation:

c ( hypothenuse ) = 7

to find a, use sine

Sine = \frac{opposite}{hypothenuse\\}

Sine 45 = \frac{a}{7}

sine of 45 is 0.707

0.707 = \frac{a}{7}

multiplt 7 on both sides:

0.707 x 7 = \frac{a}{7} x 7

a = 4.949

to find b, use cosine

Cosine = \frac{adjacent}{hypothenuse}

Cos 45 = \frac{b}{7}

cos of 45 is 0.707

0.707 = \frac{b}{7}

multiply 7 on both sides:

0.707 x 7 = \frac{b}{7} x 7

b = 4.949

Answer:

5-i

Step-by-step explanation:

Product=multiplication

Let the complex number=x

(3+2i)*x=17+7i

x=17+7i / 3+2i

x=(17-7i)*(3-2i)/(3+2i)*(3+2i)

=51-34i+21i+14i^2 / 9+6i+6i+4i^2

=51+13i+14i^2 / 9+12i+4i^2

= (51+14 - 13i) / 13

= (65 -13i) / 13

= 65 / 13 - 13 i / 13

= 5 - i.
