Answer:
52 inches
Step-by-step explanation:]
Step one:
given data
Length of one side= 10inch
Width of the other two sides= 21 inches
Step two:
The perimeter of the triangle is given as
P= L+W+W
P=10+21+21
P=52 inches
Answer:
45 degrees
Step-by-step explanation:
Answer:
e=-1/2
Step-by-step explanation:
4/3=-6e-5/3
Multiply both sides by 3:
4=-18e-5
Add 18e to both sides:
18e+4=-5
Subtract 4 from both sides:
18e=-9
Divide both sides by 18:
e=-1/2

Answer:
x = 3
y = -1
Step-by-step explanation:
x + y = 2 ---------------------(I)
x -y = 4
x = 4 + y -----------------(II)
Substitute x = 4 + y in equation (I)
4 + y + y = 2
4 + 2y = 2
Subtract 4 from both sides
2y = 2 - 4
2y = - 2
Divide both sides by 2
y = -2/2
y= -1
Substitute y = -1 in equation(II)
x = 4 - 1
x = 3
