1) y = 8 x = 7.5
2) y = 3 x = 12
10^6 = 10 *10*10*10*10*10 = 1,000,000
10^2 = 10*10 = 100
1000000/100 = 10,000 times larger
Answer:
Angle BCA = 90
Step-by-step explanation:
A triangle inscribed inside of a circle using the diameter as it's hypotenuse is a right triangle
Where the angle opposite of the hypotenuse ( or diameter ) is the right angle
Angle BCA is the angle opposite of the diameter
Hence BCA = 90
Answer:

Step-by-step explanation:
Surface area ⇒ area of 2 triangles + area of 3 rectangles

The correct answer is B
When you put the values of x and y in the equation
3(3) - 4(-1) = 13
9 + 4 =13
13=13 (correct answer)
When you try putting the rest of the values in the equation the answer doesn’t match ,hence ,the correct answer is B.I hope I get the brainliest answer!
