Step-by-step explanation:
0+1 = 1
1/2+1/2= 1
-50 + 51= 1
The answer is : 2)line segment wy
Answer: 23
step by step:
The angle is 90 degrees
(2x+14) + (x+7) = 90
(2x+ x) + (14+7) = 90
3x+21 = 90 (subtract 21 from both sides)
3x+ 21 - 21 = 90 - 21
3x = 69 ( divide each side by 3)
x = 23
Answer:
Equal sides = 6cm each
Unequal side = 12cm
Step-by-step explanation:
Perimeter of a triangle = side a + side b + side c
Let
Side a = side b = x
Side c = 2x
Perimeter of the triangle=24cm
Perimeter of a triangle = side a + side b + side c
24 = x + x + 2x
24 = 4x
Divide both sides by 4
24 / 4 = 4x / 4
6 = x
x = 6
The equal sides = x = 6cm each
The unequal side = 2x
= 2(6)
= 12cm
Check:
Perimeter of a triangle = side a + side b + side c
= 6cm + 6cm + 12cm
= 24cm
