Answer:

y = 42°

Step-by-step explanation:

The third vertex in the triangle with y is adjacent to a right angle, thus is right.

The sum of the 3 angles in a triangle = 180°, then

y = 180° - (90 + 48)° = 180° - 138° = 42°

What is the sum of sqrt -2 and sqrt -18

Assoli18 [71]

Answer:

4i sqrt(2)

Step-by-step explanation:

sqrt(-2) + sqrt(-18)

We know sqrt(ab)= sqrt(a) sqrt(b)

sqrt(-1)sqrt(2) + sqrt(9) sqrt(-2)

sqrt(-1)sqrt(2) + sqrt(9) sqrt(2)sqrt(1)

We know the sqrt(-1) is equal to i

i sqrt(2) +3 sqrt(2) i

i sqrt(2) +3i sqrt(2)

4i sqrt(2)
