Answer:
2.7 The second question I am unsure of because side EF is clearly labeled 7, if they meant to ask for the value of x in the second question then your answer is 12
Step-by-step explanation:
Answer:
25.5
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
A= L²
50 = L² (do opposite operation to find L)
L = 7.07
x²= L²+ L²
x²= 7.07² + 7.07²
x² = 100 ( do opposite operation to make x the subject)
x = 10
Note: opposite operation of square is square root
(X1=1, y1=7) and (x2= -4, y2 =-8)
Slope = ( y2-y1)/(x2-x1)= (-8-7)/(-4-1)= -15/-5=3
Slope is 3
Circle equation: (x - h) + (x - k) = r²
(h, k) = center
r = radius
The center is (-7, 4)
To find the radius, take the square root of 49.
√49 = 7
The radius is 7.
Best of Luck!
