To solve the exercise you can first find the measure of angles B and C in triangle ABC.
Since the triangle ABC is an isosceles triangle, then it is true that
On the other hand, the Triangle Sum Theorem, which says that the sum of the three interior angles in a triangle is always 180°.
So, the measure of angles B and C in triangle ABC will be
Then, you can see that none of the angles in triangle ABC is congruent with angle D.
Therefore, none of the angles in triangle ABC are congruent to angle D, so the triangles are not similar.
It would be distributive since you distributed the 5 to x and -2.
5*x = 5x and 5*-2 = -10
= 7.348469228
this is irrational, because it cannot be written in the form
2. Irrational
Scalene triangle would be the correct answer for this question
Answer:
46
Step-by-step explanation:
If you take the fraction and divide it 2/11, it'll give you the decimal form of what you need, which will give you .18
Now your equation has become 254*.18, which you multiply instead of divide because you switched the form it is given in, and if you try to divide it will give you some obscure number.
Your answer from 254*.18 is 45.72, which you cant give .72 of a book, therefore you round up, making it so he has donated 46 books.
