Answer:
A and C
Step-by-step explanation:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero
Answer:
Step-by-step explanation:
arc BE is the same as the interior angle, or 76°
BE = 76 °
we can also find arc CE the same way, b/c we can see that the interior angle is the suppment with 76 or 180-76 = CE or 104°
Now we know all the arcs but arc CD
so use the idea that all the way around the circle is 360°
360 = 76 + 104 + 140 + CD
360 - 76 - 104 - 140 = CD
40 = CD
CD = 40 °
Answer:
y+1 = -1(x+10)
Step-by-step explanation:
The point slope equation of a line is
y-y1 = m(x-x1) where m is the slope and (x1, y1) is a point on the line
y - -1 = -1 (x --10)
y+1 = -1(x+10)
Answer:
The Answer is C.
Step-by-step explanation:
There is only one number before the decimal point, 6. 6 ones, so we already cross out A and D as incorrect. Now we have B and C. There is only two numbers after the decimal point. The first number after the point is in the tenths place. So, B is the correct answer.

Answer:
1) option c
2) option d
3) option a
4) option a
5) option c
Step-by-step explanation:
1. Given that in ΔRST, ∠R=63°, ∠T=90° and so ∠S=27°
Also, cosec=hyotenuse/opposite side
Given RS=23 and ST=10.4
So, cosec27=RS/RT=23/RT
sec=hypotenuse/adjacent side
sec27=RS/ST=23/10.4
And cot=adjacent/opposite side
So, cot63=RT/ST=RT/10.4
2. formula:- sinθ=opposite side/hypotenuse
cosecθ=hypotenuse/opposite side
∴ sinθ *cosecθ = (opposite side/hypotenuse) * (hypotenuse/opposite side) = 1
3. Formula :- tan(360-θ) = -tanθ
∴ tan(300) = tan(360-60) = -tan30°
tan30° = √3
∴tan300° = -√3
4.
5. sinθ= opposite side/hypotenuse
cosecθ = hypotenuse/opposite side
∴ cosecθ = 1/sinθ
Given sinθ = 0.3090
∴ cosecθ = 1/0.3090 = 3.2362
