The 3 inside angles of a triangle need to = 180 degrees
you are given 70 and 80 which = 150 degrees ( 70 +80 = 150)

so the missing angle (PQR) = 180 - 150 = 30 degrees

Find the values of x and y that makes each equation true. –(5y)i+12=4x+25i

vovikov84 [41]

Equate real part and imaginary part:

LHS:

real part -- 12

imaginary part -- 5y

RHS:

real part = 4x

imaginary part = 25

Equating::

12 = 4x

x = 12/4

x = 3

Again:

5y = 25

y = 25/5

y = 5

So,

x = 3

y = 5
