∠A=8x+6 ∘ start color #11accd, angle, A, end color #11accd, equals, start color #11accd, 8, x, plus, 6, degrees, end color #11ac

zvonat [6]

Answer:

$x = 8$

$B = 70$

Step-by-step explanation:

Given

$A = 8x + 6$

$B = 4x + 38$

Require

Determine x and <B

Missing in the question: A and B are vertical angles

For vertical angles A and B,

$A = B$

Substitute values for A and B

$8x + 6 = 4x + 38$

Collect Like Terms

$8x - 4x = 38 - 6$

$4x = 32$

Solve for x

$x = 32/4$

$x = 8$

To solve for B, substitute 8 for x in $B = 4x + 38$

$B = 4 * 8 + 38$

$B = 32 + 38$

$B = 70$

lara31 [8.8K]

Answer:

w = 5

Step-by-step explanation:

In the given right triangle, by trigonometric ratio, we have:

$\tan \: 60 \degree = \frac{5 \sqrt{3} }{w} \\ \\ \sqrt{3} = \frac{5\sqrt{3}}{w} \\ \\ w = \frac{5 \cancel {\sqrt{3}} }{ \cancel {\sqrt{3}} } \\ \\ w = 5$
