Z is 90 degrees.
Y is 31 degrees
X should be 31 degrees also
Answer:
(6,2)
Step-by-step explanation:
y=-1/2x+5
y=2x-10
-1/2 x+5 =2x-10 to find the solution y=y ( point of intersection of two lines)
-1/2 x-2x = -10-5 solve for x
-5/2 x=-15
x=-30/-5=6
y=2x- 10 substitute x in the equation to get y
y=2(6)-10
y=2
The answer is A. 5/25 X5/25 =25/625 if I'm wrong I'm sorry
Divide subtract multiply, then pay attention next time lolll XD
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x
Consider the left side
← multiply numerator/denominator by (1 + sinA)
= ← expand denominator using FOIL
=
= ← cancel cosA on numerator/ denominator
=
= right side , thus proven
