Answer:
can u do my delta math? ill do it
Step-by-step explanation:
9.
Well the first has the angles being 3x+12,x,and 90 so they have to add up to 180 degrees because it is a triangle.
3x+12+x+90 = 4x+102 = 180 solve
4x+102=180
4x=78
x=19.5

Hi there!
![\large\boxed{tan45^{o} = 1}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7Btan45%5E%7Bo%7D%20%3D%201%7D)
On the unit circle, the angle at which the x-value = √2/2 and the y-value = √2/2 is at 45°.
tan 45° = (√2/2)/(√2/2) = 1.
