The answer is 0487 if you subtract
you cant factorise both of them as they have nothing in common
Answer:
The two triangles are related by SAS, so the triangles are congruent.
Step-by-step explanation:
We can see that both of them have 2 similar sides, and 1 similar angle. This goes underneath the rule SAS, which makes the triangle congruent

Answer:
D
Step-by-step explanation:
First, let's find <em>x</em>.
We know that one of the angles is 30. The side opposite to than angle is 11, and <em>x</em> is the adjacent side to it. Therefore, we can use the trig function tangent.
Recall that:

Plug in 30 for the angle, 11 for the opposite, and <em>x</em> for the adjacent. Solve for <em>x</em> by cross-multiplying:

From the unit circle, recall that tan(30) is equal to one over the square root of 3. Thus:

Now, we can use the Pythagorean Theorem to find <em>y</em>. <em>y</em> is the hypotenuse. Thus:

20. 3 notebooks
21. 2ab, the coefficient is 2
22. t = 16
