Answer:
2
Step-by-step explanation:
(2/3)3= 2× 3/3 = 2×1 (since 3/3=1)
=2
Answer:
<u>The answer is B.</u>
Step-by-step explanation:
When you have three numbers in the left bubble, and 4 on the right for "mapping a," you cant have 2 going into one number on the right. You can only have 1 number going into 2 (shown in the mapping b image).
<u>Thus, the answer will be "Mapping B."</u>
Answer:
I think 90
Step-by-step explanation:
a+c/2*m
The options are:
A) exactly one triangle;
B) no triangles;
<span>C) more than one triangle.</span>
First thing, let's see if these angles can make a triangle:
(81 + 52 + 47) = 180
We know that the sum of the inner angles of a triangle must equal 180°, therefore yes, they can be angles of a triangle.
With only the measure of the angles and nothing about the sides, we can construct as many triangles as we want: try, indeed, to construct a triangle with given angles bus sides of your choice; then, double the sides. You will get a triangle that is twice the size, but the angles remained the same.
Hence, the correct answer is C) more than one triangle.
