Given O A ‾ ⊥ O C ‾ OA ⊥ OC start overline, O, A, end overline, \perp, start overline, O, C, end overline m ∠ B O C = 6 x − 6 ∘
Sphinxa [80]

Answer:

x = 8

m∠BOC = 37°

m∠AOB = 53°

Step-by-step explanation:

If OA is perpendicular to OC, this means that <AOC = 90°

Given

m∠BOC=6x−6

m ∠AOB = 5 x + 8

The expression is true

m∠BOC+m∠AOB= m∠AOC

6x-6+5x+8 = 90

Find x:

11x + 2 = 90

11x = 90-2

11x = 88

x = 88/11

x =8

Get m∠BOC:

m∠BOC= 6x-6

m∠BOC= 6(8)-11

m∠BOC = 48-11

m∠BOC= 37°

Get m∠AOB;

m∠AOB = 90-m∠BOC

m∠AOB =90-37

m∠AOB = 53°

HI HELP ASAP PLEASE EXPLAIN HOW TO DO STUFF LIKE THIS PLEASE HELP
statuscvo [17]

Given:

∠A = 66°

AB = 5 mi

To find:

The distance from point B to point C.

Solution:

Using trigonometric ratio formula:

$\tan \theta=\frac{\text { Opposite side of } \theta}{\text { Adjacent side of } \theta}

$\tan A =\frac{\text { Opposite side of } A }{\text { Adjacent side of } A}

$\tan 66^\circ =\frac{BC}{AB}

$2.25 =\frac{BC}{5}

Multiply by 5 on both sides.

$5\times 2.25 =5\times \frac{BC}{5}

$11.2 = BC (nearest tenth)

The distance from point B to point C is 11.2 mi.
