Answer:
15 square units
Step-by-step explanation:
If you were to cut off the bottom triangle (separated by the dotted line), and put it on top of the other triangle, you would get a rectangle.
All you have to do is length x height
5 x 3 = 15
Answer:
It is similar because if you think about it 21.5 if you get rid of the 2 you have 1.5. It is different because the numbers are not on the same position on the number line
Step-by-step explanation:
A5 / a1 = r^4 = 324/4
So r^4 = 81
r = +/- 3
If r = 3 :-
S5 = 4 * (3^5-1) / (3-1) = 484
so r = 3 Answer
Answer:
45
Step-by-step explanation:
Answer:
20 degrees
65 degrees
95 degrees
Step-by-step explanation:
Add the numbers in the ratio.
4+13+19=36
Divide the sum of all the angles in a triangle by the sum of the numbers in the ratio.
180/36=5
Multiplying 5 to each of the numbers in the ratio will give the measures of the angles.
4(5)=20 degrees
13(5)=65 degrees
19(5)=95 degrees
