Answer:
C. m∠x + m∠y = 180
Step-by-step explanation:
The two straight line in the diagram intersect each other to form two pairs of vertical angles. These are <x and <z, and <y and w.
The only statement from the given options that is true is m∠x + m∠y = 180.
This is because they are angles in a straight line. The sun of angles in a straight line is 180°.
It’s quite easy here.
A sum means addition.
The term “of a number” means youre dealing with a variable.
10 is an Interger. Put those two together and you end up with:
x+10
^^ Thats your answer. Hope this was helpful.
Angle A should be equal to 47
Use the Law of Sines to find side x.<span>
x / sin(A) = c / sin(C)</span><span>
x / sin(61°) = 15 / sin(81°)</span><span>
x = (sin(61°) x 15) / sin(81°)</span><span>
x = <span>13.283
Or rounded to 13.3
