Answer:
x ≈ 7.1
Step-by-step explanation:
Using the cosine ratio in the right triangle.
cos27° = = = ( multiply both sides by x )
x × cos27° = 6.3 ( divide both sides by cos27° )
x = ≈ 7.1 ( to the nearest tenth )
Heya!
Here is your answer:
56+4339-843= x1676
3552= x1676
x = 3552/1676
x= 2.12

Answer:
see below
Step-by-step explanation:
y = x+.6
Solve for x
Subtract .6 from each side
y-.6 = x+.6 -.6
y-.6 =x
Let y = 3 y-.6 = 3-.6 = 2.4 =x x=2.4
Let y=4.2 y-.6 = 4.2 - .6 = 3.6 =x x=3.6
Let y =2 y-.6 = 2-.6 =1.4 =x x=1.4
Answer:
Angle bisector
Step-by-step explanation:
Find the measure of the angle COA. By angle addition postulate,
From the diagram,
then
Find the measure of the angle BOA. By angle addition postulate,
From the diagram,
then
Find the measure of the angle COB. By angle addition postulate,
From the diagram,
then
This means, the measures of angles COB and BOA are the same and are equal half the measure of angle COA, so angles COB and BOA are congruent. This means, the ray OB is the angle bisector of angle COA
