<em>Equation:</em>

9(a+2)=189

<em>Solve the equation:</em>

9a+18=189

9a=189-18

9a=171

a=171/9

a=19

<em>Check the solution:</em>

Let a=19

9(a+2)=189

9(19+2)=189

171+18=189

189=189


Therefore, the equation is 9(a+2)=189 and a is 19.

Answer:

8

Step-by-step explanation:

use trig functions

2 sides and 1 angle given

Sides given

  • hypotenuse -> x
  • opposite side to 30˚ -> 4

Angle

  • 30˚

trig function associated with hyp and opp is sin

sin(x) = opp/hyp

substitute

sin 30˚ = 4/x

solve for x

0.5 = 4/x

0.5x = 4

x = 8

Find x in the given circle where o is the centre of the circle?​
artcher [175]

Answer:

X as an angle will be equal to 140°

Step-by-step explanation:

As AO = BO, AOB is an Isosceles triangle which has 2 equal angles OAB=OBA=20°, therefore BOA is equal to 140°

x is the angle opposite to BOA which will have the same angle measure.
