If B is the midpoint of AC and AC=8x-20 find BC

Elza [17]

We know that AC=8x-20 and B is the mid-point of AC

⇒ AB = BC = $\frac{AC}{2}$

⇒ BC = $\frac{8x-20}{2}$

⇒ BC = 4x-10

What is the value of x sin 64°=cos x what is the value of x?

Westkost [7]

We know that

sin 64°= cos (x)
64° and x-------> are complementary angles
64°+x=90°
then
x=90-64----------> 26°
so
sin 64°=cos 26°

the answer is
x=26°
