Answer:
∠ B = 19°
Step-by-step explanation:
note ∠ C = 90° ( angle in a semi- circle )
The sum of the 3 angles in the triangle = 180°, thus
∠ B = 180° - (90 + 71)° = 180° - 161° = 19°
Answer:
Mine was multiple choice and I got c
Step-by-step explanation:
You use explicit funtion to find a particular number in the list without needing to write all the list down.
For example, the first range of number has a constant difference of 5. Its explicit funtion would be: x(n)=3+(n-1)*5 (with x is the number you need to find, n is the number's position in the range)
Basically, a explicit funtion in that problem has the form:
x(n)=f+(n-1)*d
with:
x= the number needed to find
n= the number's position
f = the first number in the range
d = the distance
Good luck!
Not an answer but Photo math is a good app to use to calculate to :)
