Answer:
x = 60°
Step-by-step explanation:
AOB Center: O AB: diameter
arc ADB = 180°
arc DB = 180 - arc AD = 80°
x = 1/2 x ( arc DB + arc AC) = 1/2 x (80 + 40) = 60°
Answer:
1,2,3,4,5
Step-by-step explanation:
Every whole number is a rational number.
The supplement of 61 degree is 119 degrees
180-61=119
To find the area of a triangle multiply half the sum of the bases by its height, i think?
12√3 / 12
Step-by-step explanation:
this creates a 30,60,90 triangle and since we are trying to find the rising part of the run we are going to have to find the 60-degree angle part. So then we do 12 times root 3.
