Answer:
24.8
Step-by-step explanation:
This is pythagorean theorem since it is a right-angled triangle.
A^2 + B^2 = C^2
Where A and B is the 2 sides that make the right angle
And C is the hypotenuse (the longest side)
So we just substitute in
19^2 + 16^2 = C^2
361 + 256 = C^2
617 = C^2
sqrt(617) = C
24.839 = C
Rounded up to the nearest tenth = 24.8
3X+9X=180
12X=180
X=15°
Angle 1=3X
Angle 1 =45°
That's your answer.

Answer:
y = 8
Step-by-step explanation:
(-6 , 8) and (8 , 8) has the same value of y coordinate 8
the line pass those two points is y = 8
