Answer:
7.5
Step-by-step explanation:
If we look at the 4 by 4 square around the triangle we can just do the area of the square minus the area of the 3 little triangles which is:
4 * 4 - 4 * 1 / 2 - 3 * 3 / 2 - 4 * 1 / 2
= 16 - 2 - 4.5 - 2
= 16 - 8.5
= 7.5
Answer:
x= 19
Step-by-step explanation:
Is given that the <u>triangles are congruent</u> so the corresponding sides are congruent as well.
Also congruent sides are equal in measure so we use the given picture to write the equality.
2x -1 = 37, add 1 to both sides
2x = 38 , divide both sides by 2
x = 19
For this case we must find the roots of the following equation:

We have to:

Where:

Substituting the values:

We have two roots:
