Answer:
42.12cm²
Step-by-step explanation:
Firs well have to find the hypotenuse of the big and small right angled triangles because it is the length of the long and short diagonals which is needed in solving
The bigger triangle
Using Pythagoras theorem
let the length be x
x²=10²+6²
x²=100+36
x²=136
√x²=√136
x=√136
x=11.7m
The smaller triangle
Using Pythagoras theorem
let the length be y
y²=6²+4²
y²=36+16
y²=52
√y²=√52
y=√52
y=7.2
Now to find the total area of the shape which is a kite
Formula=
1/2 x D1 x D2
D1 is the long diagonal which is the hypotenuse of the bigger triangle and D2 is the shorter diagonal the hypotenuse of the smaller triangle
Answer:
Step-by-step explanation:
I will show you by example. For the sin ratio, we have that the sin of the reference angle is equal to the side opposite the angle over the hypotenuse of the right triangle. We use this example for finding the ratio, knowing the angle:
found on your calculator. Because this is a special angle in a right triangle, we can also say, by looking at a 60 degree reference angle that the side across from the angle measures square root of 3, and the hypotenuse measures 2. So in terms of a radical,
If we don't know the angle, we use the 2nd button on our calculator to find it. For example, if our problem looked like this:
,
we are asked what angle has a sin ratio of 1/2. We find this angle by pressing the 2nd button on our calculator, then the sin button and you will see this on your screen:
Enter either a .5 or a 1/2 after that open parenthesis and hit enter and you'll get the angle measure. That's how you use the inverses to solve for missing angles.
