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

Answer:
15/17
Step-by-step explanation:
cos(arctan(8/15)) = 15/17
__
You could assume the ratio values 8 and 15 represent the opposite and adjacent sides of a right triangle. Then the hypotenuse is ...
h = √(8² +15²) = √289 = 17
The cosine is the ratio of the adjacent side to the hypotenuse, so is ...
cos(x) = 15/17
1)73 degrees
all the angles of a triangle add up to 180 degrees.
23+84= 107
180-107=73
2) 28 degrees
110+42= 152
180-152= 28
