THEOREM:
- Angle sum property —: The sum of interior angles of a triangle is 180°.
ANSWER:
Let the missing angle be x.
By angle sum property,
- ∠x + 20° + 80° = 180°
- ∠x + 100 = 180°
- ∠x = 180° – 100°
- ∠x = 80°
So, <u>Correct choice</u> - [C] 80°.
Answer:
( -1, 15/2) or ( -1, 7 1/2)
Step-by-step explanation:
Formula: ( (x1 + x2)/2, (y1 + y2)/2 )
1. ( (-4 +6)/2, (8 + 7)/2 ) Plug in
2. ( -2/2, 15/2) Add/Subtract
3. ( -1, 15/2) or ( -1, 7 1/2) Divide
Answer: The both triangle are not scale version to each other.
Explanation:
It is given that the one rectangle measures 2 units by 7 units. a second rectangle measures 11 units by 37 units.
The two shapes are scaled version of each other if their corresponding sides are in same proportion. In other words the if two shapes scaled version of each then the shapes are similar.
The sides or first rectangle are 2 and 7. The measures of second rectangle are 11 and 37.
The proportion of small side is,

The proportion of large side is,

So,

Since the proportion are not equal, therefore both triangle are not scale version to each other.
Answer: Neither, Both Unit Prices are equal.
Step-by-step explanation: In order to find the unit price of an item, you divide the quantity by the price. In this case, the Big Lots would be 5.88/12 which equals 49 cents. The Walmart Batteries are 8.82/18 which is also 49 cents. So both batteries are the same price, you should buy the better quality battery in this situation.
