Answer:
cos(∅) = 3/5
Step-by-step explanation:
cos(∅) = adjacent/hypotenuse
We don't know what the hypotenuse is so we gotta use Pythagorean theorem to find it.
a² + b² = c²
4² + 3² = c²
√(4² + 3²) = c
c = 5 , this is our hypotenus
cos(∅) = adjacent/hypotenuse
cos(∅) = 3/5
Answer:
10.24 in²
Step-by-step explanation:
First we need to know how to find the area of a rectangle, which is base * height.
We can notice that the base and height are both 3.2, so we multiply 3.2*3.2.
To do this, we first have to completely ignore the decimal points. Just pretend you're multiplying 32*32, to get 1024. Then, we count how many numbers are past the decimal point on each number. On both, there is 1 number past, and we add those together to get 2 numbers past the decimal point.
We then, finally, make the number we got (1024) have 2 numbers past the decimal point, so instead of 1024, we have 10.24, which is our answer!
Answer:

Step-by-step explanation:
Answer:
B. x = 14
Step-by-step explanation:
1. Add 9 to both sides of the equation
x - 9+9 = 5+9
x = 14
hope this helps :)
