Answer:
in term of x
Step-by-step explanation:
Given that AB is tangent to a circle with center O and radius of OC=OB
D is the mid-point of the chord BC and D is 90
Here, Angle BAC = x.
From figure,
AC is a straight line.
we can write as
Since D is the mid-point of the chord BC
We know,
Angle opposite to sides are congruent
So,
Now, In triangle AOB
Therefore,
Therefore.
Thus,

You can calculate percentages by first finding what 10% of a value is and then what 5 or 1% is. From there you can multiply to find multiples and then add to get the required percentage. The example below shows this.
<span>What is 35% of $40?<span>Step 1<span>What is 10% of $40?10% of $40 = $40 ÷ 10 =<span> $4</span></span><span>10% is a relatively easy percentage and can be found by<span> dividing by 10</span>.</span></span><span>Step 2<span>3 x $4 = $1230% of $40 = $12</span>30% is 3 times ( 3 x) 10% so we multiply what 10% of $40 is by 3</span><span>Step 3<span>What is 5% of $40?5% of $40 = $4 ÷ 2 =<span> $2</span></span><span>5% is half of what 10% is so divide what 10% is by 2 .</span></span><span>Step 4<span>What is 35% of $40?$12 + $2 = $14</span><span>Add what</span></span></span>
