The answer is X= 5. Using the pythagorean theorem, and assuming that "b" is 3, half of 6 because the triangle is isosceles, you can solve the problem.

Answer:
9.76
Step-by-step explanation:
area of a rectangle = length * breadth
length = (2x + 3)
breadth = x
given area is 220 sq. inches.
thus,
220 = x * (2x+3)
220 = 2x² +3x
2x² + 3x -220 = 0
x = (-b + √ ( b²-4ac) ) ÷ 2a
x = ( -3 + √ ( 3² - 4*2*220) ) ÷ 2*2
x =9.76
Answer:
X=1 because 2+5=7 then X=1 cause 1*2=2
Step-by-step explanation:
Answer:
x= 10
Step-by-step explanation:
If line m is parallel to line n,
(8x +50)°= 130° (corr. ∠s, m//n)
8x +50= 130
Bring constants to one side:
8x= 130 -50
8x= 80
Divide both sides by 8:
x= 80 ÷8
x= 10
