Answer: x = 52° and 2x + 24 = 128°

Steps:
180 = x + (2x + 24)
180 = x + 2x + 24
180 = 3x + 24
180 - 24 = 3x
156 = 3x
52 = x

Simplify the expression by using a double-angle formula or a half-angle formula. (a) cos2 θ 2 − sin2 θ 2

SCORPION-xisa [38]

If this is supposed to be
$cos^{2}θ-sin^{2}θ$
Then this can simply be reduced to
$cos2θ$
by the double angle formula for cosine

A changes saved Set up a proportion and use it to solve for x. 2 10 х 3

V125BC [204]

Answer:

C. 15

Step-by-step explanation:

The following proportional can be set-up for the figure given:

$\frac{x + 3}{x} = \frac{10 + 2}{10}$

Solve for x

$\frac{x + 3}{x} = \frac{12}{10}$

$\frac{x + 3}{x} = \frac{6}{5}$

Cross multiply

$5(x + 3) = x(6)$

$5x + 15 = 6x$

15 = 6x - 5x

15 = x

x = 15
