m before the angle symbol stands for angle
angle acb = 180 - 108 = 72 degrees
180 = a+b+ angle acb
180 = a + 32 +72
180 = a + 110
A = 70
Is there an amount of the 3-liter bottles?
Answer:
Perimeter 18.8
area 15
Step-by-step explanation:
Use pythageriums theorem
6^2 + 5^2 = c^2
I found the sides by counting squares
6^2 + 5^2 = 61
square root it to find the answer
7.8 is the missing side so now add it all together
7.8+6+5= 18.8
to find the area do 6 x 5/ 2
so the answer is 15
Answer:
Angle b is 90 degrees. If angle a is 42 degrees and it is a right triangle then angle b is 90 degrees
