These 3 objects are used to make all of the other objects that we will use in geometry
Answer:
The experimental probability of the outcome is 1/4
Step-by-step explanation:
If Samuel's experiment probability was 0.25, this depicts that the experimental probability of the outcome is 1/4, because:
1/4=0.25
It's not the theoretical probability, because Samuel's developed an experiment, it cannot be theoretical, he has experimental evidences.
A straight line adds up to 180
So the line opposite of 137 should add up to 180
This gives us the equation 137+x=180 then x=43
The triangle also adds up to 180 degrees
So 102+43+x=180
The equation can be simplified to 145+x=180 therefore x=35
So x+?=180 because it is a straight line.
We can substitute x in making the equation 35+?=180
Now we want to solve for the ? so we'll subtract 35 from each side
This leaves us with the equation ?=145
So we now know that the ?=145
Answer:
=14.69km²
Step-by-step explanation:
We can use the Hero's formula to calculate the area
A= √(s(s-a)(s-b)(s-c))
s is obtained by adding the lengths of the three sides of the triangle and then dividing by 2, a, b and c are the ides of the triangle.
S=(5+6+7)/2
=9
A=√(9(9-6)(9-5)(9-7))
=√(9×3×4×2)
=√216
=14.69km²
Answer:
O = 50.3 degrees
Step-by-step explanation:
tan O = 89/74
tan O = 1.2027
O = 50.3 degrees
