Answer:
1 + tan 2θ = sec 2θ
Step-by-step explanation:
cos 2θ + sin 2θ = 1
Dividing by cos 2θ we get
( cos 2θ + sin 2θ ) / cos 2θ = 1 / cos 2θ
1 + sin 2θ / cos 2θ = sec 2θ
And sin 2θ / cos 2θ = tan 2θ
Then
1 + tan 2θ = sec 2θ
Answer:
FM = 22
Step-by-step explanation:
Centroid of a triangle divides the median in the ratio 2 : 1
Therefore, AM : FM = 2 : 1
Let AM = 2x and FM = x
Since, AM = 44
Therefore, 2x = 44
x = 44/2
x = 22
FM = 22
Answer:
15
Step-by-step explanation:
(x+y)+5
(6+4)+5
(10)+5
15
<span>10y + 3.8 = 38.8 subtract 3.8 from both sides to isolate y
10y </span><span>= 35 divide by 10 to isolate y
y </span><span>= </span><span>3.5 is your final answer! Hope this helps</span>
