Answer:

Step-by-step explanation:

since the angle measurements of a triangle have to add up to 180, you first have to add 45 and 55. You would get 100. Then you would take that 100 and add 65, which will give you 165, which doesn't equal 180.

Answer/Step-by-step explanation:

Given that a and b are two corresponding sides of two similar figures, it follows that the ratio of their areas = a²/b².

We would use the above knowledge to solve the questions given as follows:

✔️The first pair similar of shapes:

Missing area = x cm²

Therefore,

x/9 = 8²/4²

x/9 = 64/16

x/9 = 4

Cross multiply

x = 4 × 9

x = 36 cm²

✔️The second pair similar of shapes:

Missing area = x cm²

Therefore,

x/240 = 8²/32²

x/240 = 64/1,024

Cross multiply

x*1,024 = 64*240

x*1,024 = 15,360

Divide both sides by 1,024

x = 15,360/1,024

x = 15 cm²

✔️The third pair similar of shapes:

Missing area = x cm²

Therefore,

x/40 = 3²/2²

x/40 = 9/4

Cross multiply

x*4 = 9*40

x*4 = 360

Divide both sides by 4

x = 360/4

x = 90 cm²

Determine the inverse of the function: h(x)= 2x-3/1-x

You can approach this question by writing the function as y=… as I did in the photo. Then rearrange to make x the subject. Lastly, swap the ys for xs and write as I did on the final line of my working. If you like I can explain how to rearrange the equation or answer any other questions but I think you should be able to see
