Answer:
The answer to your question is 1 = 69°
Step-by-step explanation:
To solve this problem remember that the sum of the internal angles in a triangle equals 180°.
Let the third angle of the triangle be x.
39° + 30° + x = 180
Solve for x
x = 180 - 39 - 30
x = 111°
Angle x and angle 1 are supplementary so their sum equals 180°.
111° + 1 = 180
1 = 180 - 111
1 = 69°
Radius is half of the diameter so the radius of 4 is 2
Answer:
okkkkkk are you ok like actually
You look at the hundreths place (4) and if it is 5 or more you round the tenths place up. so the number is rounded to 9.2
