Answer:
A= 150°
B=30°
C=150°
Step-by-step explanation:
Since a line is 180°, you can write an equation for C. C+30°=180° , from here use algebra to find C. The value of C will be 150°. When the value of C is 150° , since they're supplementary angles, the value of A will also be 150°.
Important thing to note:
The value of all these angles combined together is 360°.
Answer:
78.5
Step-by-step explanation:
This is because of the formula r^2pi since 5^2=25 and 25x3.14 it equal 78.5
C) 18 because you could get 6 numbers with red, 6 numbers with brown and 6 numbers with yellow.
