Answer: $161
Step-by-step explanation: Subtract $808 from $969
Answer:
A. 17°
Step-by-step explanation:
We know that point r is 73° and point p is a right angle (90°) all triangles equal 180° on the inside. If you add 73 and 90, you get 163. Then subtract 163 from 180 to get 17.
Tan x /(1 +sec x) + (1+sec x) /tan x
Tan x=sin x / cos x
1+ sec x=1 +1/cos x=(cos x+1)/cos x
Therefore:
tan x /(1 +sec x) =(sin x/cos x)/(cos x+1)/cos x=
=(sin x * cos x) / [cos x* (cos x+1)]=sin x /(Cos x+1)
(1+sec x) /tan x=[(cos x+1)/cos x] / (sin x/cos x)=
=[cos x(cos x+1)]/(sin x *cos x)=(cos x+1)/sin x
tan x /(1 +sec x) + (1+sec x) /tan x=
=sin x /(Cos x+1) + (cos x+1)/sin x=
=(sin²x+cos²x+2 cos x+1) / [sin x(cos x+1)]=
Remember: sin²x+cos²x=1⇒ sin²x=1-cos²x
=(1-cos²x+cos²x+2 cos x+1) / [sin x(cos x+1)]=
=2 cos x+2 / [sin x(cos x+1)]=
=2(cos x+1) / [sin x(cos x+1)]=
=2 /sin x
Answer : tan x /(1 +sec x) + (1+sec x) /tan x= 2/sin x
Answer:
z=2
Step-by-step explanation:
2z-6=2(2+2)-10 Distribute.
2z-6=4+4-10 Combine like terms.
2z-6=-2 Add 6 on both sides.
<u>+6 +6</u>
2z=4 Divide by 2 on both sides.
<u>/2 /2</u>
z=2
Hope this helps! Have a great day ^^
