It's A. Sorry I can't explain.... It's obviously A
Step-by-step explanation:
angle S + angle W + angle STW = 180
(7x + 6) + (7x + 1) + angle STW = 180
So angle STW = 180 - (7x + 6) - (7x + 1)
angle STW + angle STP = 180 (straight angle = 180)
180 - (7x + 6) - (7x + 1) + angle STP = 180
angle STP = 180 - 180 + (7x + 6) + (7x + 1)
= 7x + 6 + 7x + 1
= 14x + 7
15x = 14x + 7
x = 7
angle STP = 15x = 15(7) = 105
Answer:
Step-by-step explanation:
Let A1 be the area of one square and A2 be the area of second square
So,
A1 = s^2
where s is side of square
So side of one square is
To calculate the length of fence we need to find the perimeter of the square
So,
P1 = 4 * s
For second square:
The perimeter will be:
So the total fence will be: P1+P2
a. ((x2-x1)^2 + (y2-y1)^2)^(1/2)
(-4-8)^2 + (1-5)^2 144+16= 160
160^(1/2)= 12.64
b. (8-4)/2 & (5+1)/2
4/2=2 6/2=3
(2,3) is the midpoint of AB

Explanation:
1. ΔABC ≅ ΔDEF . . . . . 1. SAS postulate*
_____
The two given congruent sides are either side of the given congruent angle, so the SAS postulate applies. The objective appears to be irrelevant.
