Answer:
60º
Step-by-step explanation:
The two triangles on the left are equilateral as the sides are all conguent.
The angles of an equilateral triangle are all 60º
Therefor the two angles to the left of angle 1 are both 60º for a combined value of 120º
Angle 1 must be 180 - 120 = 60º
Answer:
Option B. is correct.
Step-by-step explanation:
Since LMNO is a parallelogram, so the opposite sides of the parallelogram LMNO will be equal.
Hence, LM =NO and NM = OL. {Those are opposite sides}
Now, given that NM =x+6 and OL = 2x+3.
Hence, x+6 =2x+3
⇒ x= 3.
Therefore, NM =x+6 =3+6 =9 units and OL = 2x+3= 2×3+3 =9 units.
So, option B. is correct. (Answer)
Answer:
(3x+5)(3x−5)
Step-by-step explanation:
Given:
Miguel needs to cut a board that is Two-thirds of a yard long into 3 equal pieces.
To find:
The expressions that can you use to find the length of each piece.
Solution:
It is given that Miguel needs to cut a board that is Two-thirds of a yard long into 3 equal pieces. It means 
is divided in 3 equal parts.
It can be written as:
Therefore, the required expression is and the length of each piece is 
yards.
