Answer:
<A= 65 & <B=78
Step-by-step explanation:
this is because first we must find X, so in order to do so we must add together all angle measures, then make that equal 180. So
(2x-9)+(2x+4)+x=180
2x+2x+x-9+4=180
5x-5=180
5x=180+5
5x=185
X=185/5
x=37
Then we just have to plug in the value of x into the angle measurements.
We can put this word problem into an equation.
1/3x = 7
Now we just have to solve for x. To find x we need to multiply by three on both sides.
1/3x = 7
*3 *3
-------------
x = 21
So it will take 21 hours to paint one wall.
Answer:
A would be correct.
Step-by-step explanation:
Just show that triangles AOB,BOC,COA are all congruent (then all the sides of triangle ABC must be equal). To show this, note that triangles A′BO,A′OC are equilateral since they are all radius of the circles. Line OA′ is perpendicular to line BC. Hence, ∠OBC=∠OCB=30∘.
