Answer:
A,C
Step-by-step explanation:
sin 2x=sin (x+x)=sinx cos x+cos x sin x=2 sin x cos x
or =2 cos x sin x
[sinx cox=cos x sin x ]
That’s a rectangle not a triangle lol
In the given diagram, the measure of angle DAE is 48°
<h3>Circle Geometry </h3>
From the question, we are to determine the measure of angle DAE
From the given information,
96° is the angle subtended by the arc at the center of the circle
From one of the circle theorem,
Angle at the center is <u>twice</u> the angle at the circumference
∴ 2 × ∠DAE = 96°
∠DAE = 96°/2
∠DAE = 48°
Hence, the measure of angle DAE is 48°
