Y=64
79+37=116
180-116=64
all angles of a triangle adds up to 180
add the two given angles and subtract that from 180 to find the missing angle
Hey there!
First, let's find s:
s = (5 + 6 + 7) /2 = 9
Second, let's plug in the numbers into the formula:
A = 
Third, let's simplify the numbers to get one number under the square root:
A = [tex]\sqrt{216}
Fourth, we'll find the square root of 216 to get the area:
A = 14.697
Therefore, your answer is A.
Hope this helps!! :)
Answer:
diameter = 2.5 feet
Step-by-step explanation:
Circumference of a circle is given as C = πd
Circumference of the tree trunk = 7.85 ft
π = 3.14
Diameter of the tree trunk = d
Thus:
7.85 = 3.14*d
Divide both sides by 3.14
7.85/3.14 = 3.14*d/3.14
2.5 = d
d = 2.5 ft
