C, 51 because acute angles are less than 90° but together the angles create a right triangle which is 90°.
Diagonal of a rectangle formula:
Diagonal = √l² + w²
Diagonal = √10² + 8²
Diagonal = √100 + 64
Diagonal = √164
Diagonal = 12.806 feet.
Or you can use the pythagorean theorem. The diagonal of a rectangle is the hypotenuse of a triangle.
a²
+ b² = c² ; where a and b represents the lengths of the triangle and c
is the hypothenuse. In this case, the lengths are 10 ft and 8ft.
10² + 8² = 100 + 64 = 164 ; This represents c².
c = √c² = √164 = 12.806 ft
Answer:you multiply them? 0.205x0.234
Step-by-step explanation:
Answer: x + 1 = 15
Step-by-step explanation:
solve -
x= 15 - 1
x = 14
x is a variable so it's not fix value in math
