What is the missing angle in the right triangle?
Ainat [17]

Answer:

68

Step-by-step explanation:

For angle A, 3 is the adjacent leg. 8 is the hypotenuse.

The trig ratio that relates the adjacent leg to the hypotenuse is the cosine.

\cos A = \dfrac{adj}{hyp}

\cos A = \dfrac{3}{8}

\cos A = 0.375

We know the cosine of angle A equals 0.375. We take the inverse cosine of 0.375 to find the measure of the angle.

A = \cos^{-1} 0.375

A = 68^\circ

Solve the following equation by transforming it into a perfect square trinomial.* 3x2 + 12x = 63
Eddi Din [679]
3x^2 + 12x = 63\\ \\3x^2+12x-63=0\\ \\3(x^2+4x-21)=0\\ \\3[x^2+4x+3x-3x-21] =0 \\ \\3[x^2+7x-3x-21] =0 \\ \\3[x(x +7 )-3(x+7)] =0

3 (x +7 ) (x-3) =0 \\ \\x+7=0 \ \ \ or \ \ \ x-3 =0\\ \\x=-7 \ \ \ or \ \ \ x=3
