Answer:
x = -3
Step-by-step explanation:
The vertex lies on the axis of symmetry, whose x-coordinate is halfway between -9 and 3: x = -3
Answer:
2x=80°
x=40°
40°+20°=60°
Step-by-step explanation:
all triangles are 180°
The equation is y = -3/2
this is because the line crosses zero on the Y axis so there is no Y intercept
and to get the slope you just see how many units down & then right you need to get from the center point to the one more down
Since a triangles angles add up to 180 you would add the other sides and then
180-161=19
So angle 1 is 19 degrees
Answer:
36.87°
Step-by-step explanation:
sin(A)/a = sin(C)/c
sin(x)/3 = sin(90)/5
sin(x)/3 = 0.2
sin(x) = 0.6
x= sin^-1(0.6)
x = 36.86989765
