A = p + prt

The above equation can be solved for “r” in such a way.

Subtract “p” from both sides;

A – p = p + prt – p

A – p = prt

Divide both sides by “p” and “t”;

A/pt – p/pt = prt/pt

A/pt – 1/t = r

Given the value of cos 25° ≈ 0.9063, enter the sine of a complementary angle. Use an expression relating trigonometric ratios of

Nookie1986 [14]

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:

$Sin A\textdegree =Cos \ B\textdegree\\\\Cos \ A\textdegree=Sin \ B\textdegree$

Therefore,

The complementary angle of 25° is 65°

Cos 25°=Sin65°=0.9063
