Hello!
First of all, let's find A. This is the opposite and hypotenuse we will be dealing with. Therefore, we will use the sin.
sin30= 0.5
This gives us the equation below.
a/12=0.5
a=6
Now we find b. This is the adjacent and hypotenuse. Therefore, we will use the cosine.
cos30≈0.87
This gives us the equation below.
b/12=0.87
b=10.44
I hope this helps!
Answer:
All squares are rectangles. Rectangles have 4 right angles. Therefore, all squares have 4 right angles.
All recatangles have 4 angles which are 90°. Though all squares are rectangles, remember, not all rectangle are squares
Hope this helps, Bye!
Right answer is:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.
Step-by-step explanation:
Lets define the terms first
An independent variable is a variable whose values are put in the function. It is the input of a function.
While dependent variable's value depends on the independent variable.
Given function is:

By observing the function, we can see that the function is in terms of t which means that t is the input for the function while h is the name of the function. h(t) which be obtained by putting the values of t is the output.
So,
Right answer is:
h is the function name; t is the input, or independent variable; and h(t) is the output, or dependent variable.

3.89 rounded to the nearest tenth is 3.9
You go to the tenths place which is 8, and then go to the number next to it. 9 is greater than 5, so you have to round up.
You regroup and get 3.9

ok so he is owing his sister 24 and he gives her 15
so 24-15=9
but as an addition expression it will be
x+15=24
x=24-15
x=9
