Answer:
angle 1 is 39
angle 3 is 51
Step-by-step explanation:
Here, we want to get the value of angle 1 and angle 3
Let’s have the meeting point of the diagonals as E
Hence , ADE is a right triangle
Thus,
39 + angle 3 = 90
angle 3 = 90-39
angle 3 = 51
Furthermore;
we can see that ABD is isosceles, meaning that the base angles are equal
Thus, we have it that;
angle 3 and angle at B (for AEB triangle) are equal in values
So, we can conclude that the angle is 51 too
so if the angle is 51 too, then the triangles ADE and ABE are similar
That simply means angle marked 1 is 39
Answer:
5
Step-by-step explanation:
the answer is somewhere by 5
A a dilation and reflection
dilation will make bigger or smaller therefore it cannot be congruent

I hope this will help you
If this is incorrect forgive meplz
Answer:
f(3) = 71
Step-by-step explanation:
f(x) = 10(x + 5) − 9
f(3) = 10(3 + 5) - 9
f(3) = 10(8) - 9
f(3) = 80 - 9
f(3) = 71
