So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles
Answer:
Step-by-step explanation:
Answer:
20%
Step-by-step explanation:
%
Cross multiply to find your answer
x/250 = 20/100
250 X 20= 5000
5000=100x
x = 50
250 - 50 = 200
Answer:

Part 3) 
Step-by-step explanation:
<u><em>The question in English is</em></u>
Expressed in algebraic language.
Symbolically write the following expressions:
Three times a number:
Four times a number:
Two-thirds of a number
Let
n ----> the number
Part 1) we have
Three times a number:
we know that
The algebraic expression is equal to multiply 3 by the number n
so

Part 2) we have
Four times a number:
we know that
The algebraic expression is equal to multiply 4 by the number n
so

Part 3) we have
Two-thirds of a number
we know that
The algebraic expression is equal to multiply the fraction 2/3 by the number n
so
