Answer:
I think the answer you got is correct.
3 out of 7 would be the answer
Given:


To find:
The value of x and measure of angle A
Solution:
Alternate interior angle theorem:
If two parallel lines cut by a transversal, then the alternate interior angles are congruent.
⇒ m∠A = m∠B

Add 18° on both sides.


Subtract 3x from both sides.


Divide by 2 on both sides.
⇒ x = 30°
Substitute x = 30° in ∠A.
m∠A = 5x - 18°
= 5(30°) - 18°
= 150° - 18°
= 132°
The measure of ∠A is 132°.
Answer:
C
Step-by-step explanation:
When an equality has a ≤, or ≥ sign (greater than/less than or equal to), the line will be solid. When an equality has a <, or > sign(greater than/less than), the lines will be dotted. As we can see, both of the inequalities given have <, or >, meaning they must both have dotted lines. Since one of the lines in D is solid, the correct answer is C.
Answer:
19.21
Step-by-step explanation:
When you draw this out, it forms a right angled triangle with h = 12miles, and base = 15 miles.
So, the distance between them = the hypotenuse of this triangle.
Square root of (15^2 + 12^2) = 19.209...
Round to nearest hundredth = 19.21.
Hope this helps
