Answer: It looks like you are missing the question here. Most of the time in this type of questions, we are looking for the 3rd angle.
Let's assume that you need the 3rd angle.
There are 180 degrees in a triangle. We know 2 of the angles, so by subtracting them from 180 we can find the 3rd angle.
180 - 45 - 60 = 75
Angle C is 75 degrees. In the similar triangle Angle R is also 75 degrees because the corresponding angles are congruent.
I do khan academy 2 but sorry the answer
Answer:
Sure Amaya , the grouping is the parenthesis, right?
Step-by-step explanation:
so just add up.. the things outside of the parenthesis
- * 4
so exponents come first in the order of what to do... right?
=16 okay , got that part, the next part is
16 * 4 = 64 okay got that part, now
- 64 is what is subtracted from the grouping , got it?
Since this is a right triangle, we can use the Pythagorean Theorem, which states a² + b² = c² in a right triangle.
Plugging our numbers in, we get:
(12)² + (35)² = c²
From there, we can square the numbers.
(144) + (1225) = c²
Then, we can add them together to find the sum;
(1369) = c²
And finally, we can find the square root of both sides.
(37) = c
Therefore, 37 is the answer and your answer choice is correct.
Answer:
{(-14,9),(4,-7),(-8,6)}.
Step-by-step explanation:
To find the inverse you just swap x and y.
So if (a,b) is a point on the relation then (b,a) is on it's inverse.
So the inverse of {(9, –14), (–7, 4), (6, –8)} is:
{(-14,9),(4,-7),(-8,6)}.
