Help me please solves this my math teacher will yell at me if I don’t get this done!!!
VARVARA [1.3K]
The answer is 75

First you subtract 180 and 165 to find that smallest angle inside the triangle(15). Then you add 15 and 90,the two angles you know, and do 180 - 105= 75.

The trick is that all angles inside a triangle equal 180 degrees. Hope this helps!

What is the missing justification in the proof?
nataly862011 [7]
The missing justification in the proof is
<span>B) Substitution property of equality

The expression for sin</span>² x and cos² x is substituted to the other side of the equation. Since sin x = a/c, then sin² x = a²/c². Similarly, since cos x = b/c, then cos² x = b²/c². Adding to two results to the third statement.

Solve for W:<br><br> 69=5w+9
Trava [24]
To solve for w, you would take 9 and subtract that from the 69. after that you end up with 60=5w to find w, divide both sides by 5. 60 divided by 5 is 12, giving you your answer .

What is a prime in coordinates
sweet-ann [11.9K]
When you have a point A and then transform it using a linear transformation (like rotation, reflections, etc.), we mark it as A' to say, "This is the point which corresponds to A after the transformations were applied". This establishes a link between the two, even though they may appear to be unrelated to someone looking at the graph.
