Answer:
x = 5 ; z = 70
Step-by-step explanation:
Vertical angles have the same degree measure
(13x + 45) = 110
13x + 45 = 110
-45 -45
13x = 65
/13 /13
x = 5
Complementary angles add up to 180°
110 + z = 180
-110 -110
z = 70
Answer: The correct answer is the third choice.
Step-by-step explanation: The question is asking you to look at pieces of data from the graph. The best way to do this question is to look at each question to determine whether the statement is true or false.
In looking at the each choice:
First one - The statement is true. Looking at the graph, a 40 and 50 year old person has the same average rate.
Second - The statement is true. Looking at the graph, you can see a steady decline from a 10 year old to a 20 year old person.
Third - The statement is false. A 10 year old and 20 year old do not have the same rate.
Fourth - The statement is true. A 20 and 30 year old have the same heart rate.
Answer: See the screenshot below.
Explanation:
We'll be using these trig functions
- sine = opposite/hypotenuse
- cosine = adjacent/hypotenuse
- tangent = opposite/adjacent
The inverse of those help us find the angle. Notation like arcsine is the same as inverse sine denoted as 
on many calculators.
The decimal results are approximate.
Answer:
1/16, 1/32, and 1/64
Step-by-step explanation:
The denominator is multiplying by 2 while the numerator stays the same.
