Answer:

The answer to your question is:

Step-by-step explanation:

Data

B = 70°

c = 14

Process

sin Ф = b / c

b = c sinФ

b = 14 sin 70

b = 14 x 0.94

b = 13.16

cos Ф = a/c

a = c x cos Ф

a = 14 cos 70

a = 14 x 0.34

a = 4.76

C = 90° it is a right angle

A = 180 - 90 - 70

A = 180 - 160

A = 20°

Find the diameter of the circle. Assume the leg of the triangle is tangent to the circle. Round any decimals to the nearest tent

Anvisha [2.4K]

Answer:

8.7 units

Step-by-step explanation:

Given is a right angled triangle (because the segment with 5 units length is tangent to circle. Tangent is perpendicular to RADIUS or diameter)

Let the length of the diameter be d units

By Pythagoras Theorem:

$d = \sqrt{ {10}^{2} - {5}^{2} } \\ = \sqrt{100 - 25} \\ = \sqrt{75} \\ = 8.66025404 \\ = 8.7 \: units$

I need to know the steps

vaieri [72.5K]

YES. She is correct.

$\dfrac{x}{16}=4\qquad\text{multiply both sides by 4}\\\\\not\!4^1\cdot\dfrac{x}{16\!\!\!\!\!\diagup_4}=4\cdot4\\\\\dfrac{x}{4}=16$

Equations are equivalent

Their solutions:

$\dfrac{x}{16}=4\qquad\text{multiply both sides by 16}\\\\x=4\cdot16\\\\\boxed{x=64}\\----------\\\\\dfrac{x}{4}=16\qquad\text{multiply both sides by 4}\\\\x=16\cdot4\\\\\boxed{x=64}$
