Answer:
The measure of ∠BAC is 30°
Step-by-step explanation:
<h3><u>Given:</u></h3>
BAC = (x + 10)°
DAE = (2x - 10)°
Here, BAC and DAE are vertical angles, So they are equal
BAC = DAE
(x + 10)° = (2x - 10)°
x + 10° = 2x - 10°
Subtract 10° and 2x from both side we get,
x + 10° - 10° - 2x = 2x - 2x - 10° - 10°
-x = -20°
x = 20°
Here, The value of x is 20°
Now, We want to find ∠BAC
So,
∠BAC = (x + 10)° = 20° + 10° = 30°
Thus, The measure of ∠BAC is 30°

Step-by-step explanation:
Remember the identity sin²x + cos²x = 1.
Therefore 1 - cos²x = sin²x and 1 - sin²x = cos²x.
sqrt(1 - cos²x) / sinx + sqrt(1 - sin²x) / cosx
= sqrt(sin²x) / sinx + sqrt(cos²x) / cosx
= sinx / sinx + cosx / cosx
= 1 + 1
