Answer:
are u serious this is the most easiest question ive ever answered but the answer is 9 because u can minus 12-3 and get 9 so x=9
Step-by-step explanation:
This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.
Answer:
Cos 25°=Sin65°=0.9063
Step-by-step explanation:
-Complimentary angles generally refer to the two acute angles of a right triangle.
-The two angles add up to 90º.
Let A and B be the two acute angles. Their trigonometric relationship is such that:
Therefore,
The complementary angle of 25° is 65°
Cos 25°=Sin65°=0.9063
Answer:
f(x+1) = 2x+1
Step-by-step explanation:
f(x+1) = 2x-1
replace x w/ x+1
2(x+1)-1
distribute 2 to x+1
2(x) = 2x, 2(1) = 2
2x+2-1
subtract 2-1
2x+1
f(x+1) = 2x+1
