138° + w° = 180° (sum of angle on a straight line)
w° = 180° - 138°
w = 42

19° + x° + w° = 90°
sub. in w=42,
19° + x° + 42° = 90°
x° = 90° - 19° - 42°
x° = 29°
x = 29

Given cos theta=4sqrt2/7 find sin theta

m_a_m_a [10]

Answer:

$sin \theta=\sqrt{17}/7$

Step-by-step explanation:

<h3>Given</h3>

$cos \theta=4\sqrt{2}/7$

$sin \theta$

<h3>Solution</h3>

Use identity:

$sin^2x+cos^2x=1$

Substitute and find:

$cos^2 \theta=(4\sqrt{2}/7)^2$
$cos^2 \theta=16*2/49=32/49$

$sin \theta=\sqrt{1-cos^2 \theta} = \sqrt{1-32/49} =\sqrt{17/49} =\sqrt{17}/7$
