Step-by-step explanation:
The answer is A.
Answer:
C 117
Step-by-step explanation:
<2 = 63 vertical angles
<2 = <4 alternate interior angles
<4 + <7 = 180 straight line
63 +<7 = 180
subtract 64 from each side
<7 = 180-63
<7 = 117
Answer:
x=2
Step-by-step explanation
5x-10=0
fist add 10 to both sides to cancel the -10 on the left side
5x=10
then divide both sides to cancel the 5 in front of the x and to get the x all by itself
x=2
and then you have your answer!
Answer:
sinx = p/h , cosx = b/h , tanx = p/b
you can use these relations
Step-by-step explanation:
p = perpendicular = side opposite to the angle
h = hypotenuse = side opposite to the right angle
b= base
if no angles are given, p and b can be interchanged
