Answer: First option.
Step-by-step explanation:
You know that the product obtained by multiplying a binomial and a trinomial is:
Then, in order to simplify this product, it is necessary to add the like terms.
Therefore, the expression that is equivalent to this product after it has been fully simplified is:
You can observe that this matches with the first option.
To answer this, we need to use the rules of geometric shapes. An equilateral triangle is equiangular, meaning all its angle measures are equal. Since all triangles' angles add up to 180°, simply divide 180 by three to find the angle measure of each angle:
Therefore, the measure of the triangle's angle is 60°
Next, we know that a characteristic of a rectangle is that each angle must be a right angle, or an angle with a measure of 90°.
Now, all we have to do is use the sum of all the angle measures to figure out the missing piece:
The missing angle measure, angle x, equals 18°.
Hope this helps!
