Since triangle ABC is isosceles, then angles 1 and 9 are congruent.

4x + 3 = 9x - 47

-5x = -50

x = 10

m<1 = 4x + 3 = 40 + 3 = 43

m<1 = m<9 = 43

Triangle DBE is equilateral, so it is also equiangular.

m< 4 = m<5 = m<6 =60

Angles 3 and 8 are supplementary to congruent angles that measure 60 deg, so 180 - 60 = 120, so

m<3 = m<8 = 120

For angles 2 and 7, use the sum of the measures of the angles of a triangle is 180 deg.

m<1 + m<2 + m<3 = 180

43 + m<2 + 120 = 180

m<2 + 163 = 180

m<2 = 17

m<2 = m<7 = 17

Find the value of k given that logk - log (k-2) = log5
victus00 [196]

k = \frac{5}{2}

using the ' laws of logarithms '

log x - log y = log ( \frac{x}{y})

logx = logy ↔ x = y

logk - log(k - 2) = log5

log ( \frac{k}{(k - 2)} =log 5

\frac{k}{(k - 2)} = 5

5(k - 2) = k

5k - 10 = k

4k = 10 ⇒ k = \frac{10}{4} = \frac{5}{2}

(Refer to the attached image)​
RSB [31]

Answer:

missing side: 133 cm

Explanation:

Provided <u>2 length sides</u> and <u>one angle</u> also need to find <u>one missing side</u>.

So, use cosine rule:

⇒ a² = b² + c² - 2bc cos(A)

<u>Insert values</u>

⇒ g² = 166² + 147² - 2(166)(147) cos(50)

⇒ g² = 17794.3935

⇒ g = √17794.3935

⇒ g = 133.3956

⇒ g = 133          (rounded to nearest whole number)
