A,,,,they are multiples of the lengths indicated
The area of ABC is ...
... area = (1/2)(BE)(AC) = (1/2)·3·4 = 6
The triangles ABC and ADC are congruent, so ...
... the area of ∆ADC is 6 square units.
_____
A reflected image is congruent with its pre-image.
11: To add 3/8 and 2/5 you need to find the least common denominator (in this case 40), and change both fractions by multiplying to get the least common denominator and add them together
2/8 = 10/40
2/5 = 16/40
16/40 + 10/40 = 26/40 = 13/20
12 a: 5/6 = 45/54
4/9 = 24/54
45/54 - 24/54 =21/54
b: 7/10 = 56/80
3/8 = 30/80
56/80 = 30/80 = 26/80 = 13/40
Answer:
x = 152 degrees.
Step-by-step explanation:
The way the 2 angles are positioned indicates that they are corresponding angles.
Corresponding angles are equal.
x = 152 degrees.
Make you know what corresponding angles are and when they can be used. Make sure you also know what parallel lines are (2 or more lines whose distance is a constant). Make sure you also know what a transversal is (a line that crosses the parallel lines).
