Answer:
1. acute angle with 74°
2. acute angle with 55°
Step-by-step explanation:
any angles less than 90° is acute
any angles that are 90° are right angles
any angles over 90° above are obtuse
Answer:
Each side is 15 ft
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
225 ft^2 = s^2
Take the square root of each side
sqrt ( 225 ft^2) = sqrt ( s^2)
15 ft = s
Each side is 15 ft
The second choice is correct
X=7
after you remove parentheses you do those steps
I think you mean to find b in terms of the constants a, c and d.
(x + a ) / b - c = d
(x + a) / b = c + d
Cross multily:-
x + a = b(c + d)
b = (x + a) / (c + d)
