Answer:
tan 198 = 0.3249
sin 164 = 0.2756
Step-by-step explanation:
To find trig values of any angle, use a calculator with the trig buttons sin, cos, and tan.
First type the angle 198 into the calculator. Then press tan.
tan 198 = 0.3249
First type the angle 164 into the calculator. Then press sin.
sin 164 = 0.2756
Answer:
A variable which can can be represented in numbers is known to be a quantitative variable.
Step-by-step explanation:
A variable is described as a characteristic of an object. Their values may occur more than once for a set of data.
A variable that can be represented in numbers is known to be a quantitative variable. Arithmetic operations can also be performed on these variables i.e. after performing arithmetic operations such as addition, subtraction, multiplication or division, some numbers can still be obtained as the result.
Quantitative variables can also be compared with each other to obtain meaningful results. Quantitative variables are of two types – discrete and continuous.
Discrete variables have whole numbers as their values whereas continuous variables can even have values in between the whole numbers.
Examples of quantitative variables are height, weight, time in the 100-yard dash, the number of items sold to a shopper.
We are tasked to solve the three angles given that we have the measurements of the sides such as
a = Zack to Rachel distance
b = Rachel to Maddie distance
c = Maddie to Zack distance
a =3
b =2.5
c =4
Solving the angles we need to use Law of Cosines:
cos A = 2.5² + 4² -3² /2*2.5*4
A = 48.59°
cos B=3² + 4² - 2.5² / 2*3*4
B = 38.625°
C=180 - 48.59° - 38.625°
C= 92.79°
The three angles are 48.59°,38.63° and 92.79°.
Answer:
9 years
Step-by-step explanation:
Jacob will be half his uncle's age when his age is equal to the difference in their ages.
__
The difference is 33 -12 = 21 years. Jacob will be half Todd's age in 21 -12 = 9 years, when Jacob is 21 and Todd is 42.
Where does the 0 come into play? If it's just a random number move the decimal from the end of the number (0625.) in two places where it would be 06.25
