Use the circle to solve for the missing measures. Assume lines that appear tangent are tangent. Do NOT round any answers.

wlad13 [49]

The given circle having two external tangents, according to circle

theorem, have the following values;

r = 3

m∠1 = 82°

m∠2 = 49°

x = 82°

<h3>How can the radial length and angles be found?</h3>

r² + 1.6² = (0.4 + r)²

(0.4 + r)² - (r² + 1.6²) = 0

0.8·r - 2.4 = 0

0.8·r = 2.4

r = 2.4 ÷ 0.8 = 3

r = 3

y = 49°

From the two tangent angle theorem, we have;

m∠1 = ((82 + 98 + 82) - (360 - ((82 + 98 + 82)))) ÷ 2 = 82

m∠1 = 82°

According to circle theorems, angle at the center is twice angle

subtended at the circumference.

m∠2 = (360 - (82 + 98 + 82)) ÷ 2 = 49°

m∠2 = 49°

The length of the chord subtended by the arc x is equal to the length of

the chord subtended by 89°, which gives;

x = 82°

What value for x makes the equation 11x – 10 = 4(x + 2) + 10 true?

Mariulka [41]

11 x - 10 = 4 ( x + 2 ) + 10
11 x - 10 = 4 x + 8 + 10
11 x - 4 x = 8 + 10 + 10
7 x = 28
x = 28 : 7
x = 4
Answer: A ) 4

Please give the correct answer and no links!

Answer:

KL ≈ 16.6 ft

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos25° = $\frac{adjacent}{hypotenuse}$ = $\frac{MK}{KL}$ = $\frac{15}{KL}$ ( multiply both sides by KL )

KL × cos25° = 15 ( divide both sides by cos25° )

KL = $\frac{15}{cos25}$ ≈ 16.6 ft ( to the nearest tenth )
