Answer:
x = 11.25
Step-by-step explanation:
-6 = 0.8x - 15
Add 15 to both sides;
-6 + 15 = 0.8x - 15 + 15
9 = 0.8x
Divide both sides by 0.8;
x = 11.25
Answer:
idk what you asking but if it solve for for x it going be no solution
Answer:
15
Step-by-step explanation:
By the diagram, you can see the sum of segment AB and segment BC is segment AC. Adding the given expressions for AB and B is 
. Simplifying the equation 
, gives 
. Substituting in the equation for segment AC gives 15.
Answer:
The measure of angle θ is 7π/6. The measure of its reference angle is <u>210°</u>
and sin θ is <u>-1/2</u>.
Step-by-step explanation:
The correct question is:
<em>The measure of angle θ is 7π/6. The measure of its reference angle is ___</em>
<em>and sin θ is ___</em>
180° is equivalent to π radians. To transform 7π/6 radians to degrees, we have to use the following proportion:
180° / π radians = x° / (7π/6 radians)
x = (180/π) * (7π/6 radians)
x = 210°
And sin(210°) = -1/2
