The sum of angle around a point equal 360°
so (BOA) = 360-250=110°
and the sum of angle in the shape CAOB = 360°
so BCA = 360-(110+90+90)= 70°
THE ANSWER IS C.70°

Can i have some help
Andrews [41]

Answer: g(x) = 3/2 x + 9

Step-by-step explanation:

h(x) = -2/3 x - 1

perpendicular lines always have the opposite sign, reciprocal slope

so, the slope of the perpendicular line would be: m = 3/2

y = mx + b

y = 3/2 x + b

plug in (-4, 3) to find b

3 = 3/2 (-4) + b

3 = -6 + b

b = 9

y = 3/2 x + 9

g(x) = 3/2 x + 9

I need help with this please, thank​

5x+4y=8

-5x from both sides, you get 4y=-5x+8
then you divide the equation by 4.

y=-5/4x+2

10x-4y=46

-10x from both sides and you get -4y=-10x+46
divide the whole equation by -4 and you get y=5/2x + -23/2 .
