PLZ I need help QUICKLY

dimulka [17.4K]

Answer:

The angles produced are not the same...

Step-by-step explanation:

I think the problem has an error in the answers. I get 33 for b and 31 for q which is NOT correct when they are both similar. In fact, even the question symbols aren't right. They're not congruent...they are similar so the symbol should be ~ not the concurrency. Sorry you have a stupid online system.

Please solve for M<PRQ

MakcuM [25]

Answer:

$m\angle PRQ =49\degree$

Step-by-step explanation:

$m\angle PSQ = 360\degree - (128\degree + 134\degree )$

$m\angle PSQ = 360\degree - 262\degree$

$m\angle PSQ = 98\degree$

Now, by inscribed angle theorem:

$m\angle PRQ = \frac{1}{2} \times m\angle PSQ$

$m\angle PRQ = \frac{1}{2} \times 98\degree$

$m\angle PRQ =49\degree$

Find the midpoint between (-1+9i) and B=(5-3i)

sdas [7]

Answer:

2 + 3i, midpoint is (2,3)

Step-by-step explanation:

we need to find the midpoint between (-1+9i) and B=(5-3i)

To find the midpoint of two points (a+bi) and (c+di) in a complex plane,

we apply formula

$\frac{a+c}{2} + \frac{b+d}{2} i$

A = (-1+9i) and B=(5-3i)

Midpoint for AB is

$\frac{-1+5}{2} + \frac{9+(-3)}{2}i$

$\frac{4}{2} + \frac{6}{2}i$

2 + 3i , so midpoint is (2,3)
