In the Triangle BCD, Angle B is 90° since tangent and radius are perpendicular to one another.
Now, let's find Angle C using Angle sum property of a triangle.
Now, we know that Angle made by an arc on the centre is twice the Angle made by same arc on boundary of circle, hence we can infer that :
So, the required value of x is 9
Answer:
it is the first one
Step-by-step explanation:
8y + 4 = -3x in standard form is 3x + 8y = -4
Answer:
370
Step-by-step explanation:
Area of the entire thing is 20*20 = 400
You need to remove the triangle since it's not shaded, so find the area of the triangle and subtract it from the total (total = 400)
Area of triangle:
First find the height using pythagorean theorem
5*12 = 156
Then divide by two: 60/2= 30
400-30 = 370
Answer:
Step-by-step explanation:
Now we open the brackets first
We take the like terms together
Like terms are those terms which have same degree of x with them. Constant terms are also like terms
Simplifying the like terms
Hence this is our answer
