Parallel lines are both vertical and they don’t meet.
The measurement of angle x is 40°. these two triangle are congruent so their sides share the same length and their angles share the same degrees
Answer:

Step-by-step explanation:
Given

Solving (a): Multiplication sentence

Rewrite of as *

Solve

Hence, the multiplication sentence is:

Solving (b): Rectangular fraction model
In (a) above, the result is 2/5
The fraction model will be represented as thus:
- Draw a rectangle
- Partition in to 5 equal parts (5 represents the denominator)
- Shade 2 of the 5 partitions (2 represents the numerator)
