Answer:
A D E
Step-by-step explanation:
the figure shows that ABC is 90 degrees. So the two smaller angles add to 90 making A correct. (B isn't for obvious reasons - 180 is not 90.)
x + 4x - 85 = 90 Solve this to find the other 2 correct statements
5x - 85 = 90 Add 85 to both sides.
5x = 90 + 85 Combine
5x = 175 Divide by 5
5x/5 = 175/5
x = 35
Since ABD is a single x, that statement (D) is true.
4x - 85 = 4*35 - 85 = 140 - 85 = 55 which makes E true as well
There winning rate is 12/18=2/3. So if they continue at that same rate they will win:
162(2/3)=108 times

Step-by-step explanation:
Answer:
The answer is 6x^2-8x+2
Step-by-step explanation:
To find the area, you have to multiply the length by the width.
You will get the equation of (6x-2)(x-1). Then, you multiply and find the answer, 6x^2-8x+2.
Answer:
B. 7.2
Step-by-step explanation:
radius=24÷2= 12
other line =19.2÷2=9.6 because line from centre bisects chord and is perpendicular to it
Therefore: X²=√ 12²-9.6² ( theorem of Pythagoras)
X=7.2
