Answer:
10a: △ABC is an Equilateral triangle with all acute angles.
10b: △BCD is A scalene triangle with all acute angles.
10c: △BDE is An Isosceles triangle with one obtuse angle.
Step-by-step explanation:
10) Looking at the diagram at the bottom left;
- △ABC has 3 equal internal angles and as such, it means it will have 3 equal angles.
Thus, we can classify it as; Equilateral triangle with all acute angles.
- △BCD has 3 unequal angles. Thus, it's 3 sides are not equal. Also all the angles are less than 90°.
We can classify it as;
A scalene triangle with all acute angles
- △BDE has 2 equal angles and one angle greater than 90°. This means it has 2 equal sides.
Thus, we can classify it as;
- An Isosceles triangle with one obtuse angle.
Answer: 7:12
Step-by-step explanation:
From the question, we are informed that Adrienne has chicken and ducks on her farm and that she has 28 ducks and 48 chickens.
The ratio that describes the number of ducks to the chickens will be gotten by first representing the number of ducks to chicken as a fraction and reducing to lowest term. This will be:
= 28/48
= 7/12
= 7:12
Answer:
a
Step-by-step explanation:
do the ones that are congruent and right in front of eachother
In the Problem X=y2 the absolute variable is to be. A unit advance in y makes a change of 1/2 so the unit rate is 1/2.
Answer: 60
Step-by-step explanation: To find 50% of 120, first write 50% as a decimal by moving the decimal point two places to the left to get .50.
Next, the word <em>of</em> means multiply, so we have (.50)(120) which is 60.
This means that 50% of 120 is 60.
