first, find the numeric value for 11/15
second to find theta, simply do the <em>inverse</em> cos (which is cos^-1) of the first answer.
now you know theta, just do the sin of 90 - theta and that's it!
since you know whatr cos(theta) is, you just take the inverse cos of that number to get theta and 'reverse' cos, essentially. you are just solving for theta, by reversing the cos function with cos^-1
please mark as brainliest!

Answer:
Cost of one candy = 80 L.L.
Step-by-step explanation:
Let "x" represent cost of a candy
Cost of 12 candies = 12x
Cost of a chocolate bar = 1,250 L.L.
Total cost = 2,210 L.L.
The following equation represents the scenario given:
1,250 + 12x = 2,210
Solve for x (cost of a candy)
1,250 + 12x - 1,250 = 2,210 - 1,250 (subtraction property of equality)
12x = 960
Divide both sides by 12
12x/12 = 960/12 (division property of equality)
x = 80
Cost of one candy = x = 80 L.L.
Answer:
AB = 14 and BC = 17
Step-by-step explanation:
Congruence is a property that shows an equal relation between sides or angles of a given figure or two figures.
From the question, the given conditions are;
BC = AD, AD = 17, DC = 14, and m< 1 = m<2 .
i. Considering the property of congruence of sides,
BC = 17 (∵ BC = AD and AD has been given to equal 17)
i.e BC = AD = 17
ii. Considering the property of congruent angles and sides,
AB = 14 (∵ m<1 = m<2 and DC is 14)
Therefore, AB = 14 and BC = 17.
