THEOREM:
- Alternate interior angle —: When two lines are parallel (||) then the Same-side interior angles always add up to 180°.
ANSWER:
By alternate interior angle theorem,
- ∠3 + 90° = 180°
- ∠3 = 180° – 90°
- ∠3 = 90°
Hence, the measure of angle(∠) 3 is 90°.
Answer:
c
Step-by-step explanation:
Number of students = number of students that went to the museum / percentage of students that went to the museum
90 / 0.45 = 200 students
The first one is: k the second one is: h
