Answer: if u a math person shouldn't u know how to do it?
Step-by-step explanation:
Answer:
x= 13, angle 1= 37, and angle 2= 53
Step-by-step explanation:
So you have 2x+11+1+4x=90 degrees
If you simplify it, it becomes 6x+12=90 degrees
Then, you rearrange; 6x=90-12 or 6x= 78
So then, x=13
For angle 1 its 2x+11= 37 degrees
And angle 2 is 1+4x= 53 degrees
X=1
The length of line DF is 18
Let X represent the length of the chord.
By using Pythagoras' Theorem:
4^2 + (X/2)^2 = 15^2
(X^2)/4 = 209
X^2 = 836
X = 28.91
