Step-by-step explanation:

angle STQ is the supplementary angle (together they are 180° below line MQ) to 2x + 8.

above ST we have a group of 3 angles that combine to 180° :

2x + 8

90°

71 - x

so, to get x first :

2x + 8 + 90 + 71 - x = 180

x + 169 = 180

x = 11

so, the angle MTS =

2x + 8 = 2×11 + 8 = 22 + 8 = 30°.

therefore, the angle STQ is

180 - angle MTS = 180 - 30 = 150°.

What is the product of 5−2i and 3−4i?<br> Enter your answer, in standard form, in the box

Lelechka [254]

Answer:

$\boxed{7-26i}$

Step-by-step explanation:

The binomials are multiplied in the usual way, using FOIL or the distributive property:

(5 -2i)(3 -4i) = 15 -20i -6i +8i²

Since i² = -1, this becomes ...

= 15 -20i -6i -8 = 7 -26i

Hall and Mindy are playing a guessing game. Hall tells Mindy: ""The difference between 17 and the square root of my mystery numb

cestrela7 [59]

Answer:

The possible number that Hall could be thinking of is 144.

Step-by-step explanation:

Difference between 17 and the square root of my mystery number

This is represented by:

$17 - \sqrt{x}$

is 5

Then:

$17 - \sqrt{x} = 5$

What are two possible numbers that Hall could be thinking of?

We have to solve the equation, for x. So

$17 - \sqrt{x} = 5$

$\sqrt{x} = 12$

$(\sqrt{x})^2 = (12)^2$

$x = 144$

The possible number that Hall could be thinking of is 144.
