<h3>Answer:</h3>

25°

<h3>Step-by-step explanation:</h3><h3></h3>

<em>Angles in a circle add up to 360°</em>

5a + (a + 60) + (2a + 100) = 360

5a + 3a + 160 = 360

5a + 3a = 8a

8a + 160 = 360

<em />

<em>Make a the subject</em>

8a + 160 = 360

8a = 200

200 ÷ 8 = 25°

Answer:

23) option c

    JL ≈ 9.3

25) option c

      y ≈ 9.6

Step-by-step explanation:

<h3>25)</h3>

Given in the question that,

cos(21°) = 9 / y

y = 9/cos(21°)

y = 9.64

y ≈ 9.6(nearest tenth)

<h3>23)</h3>

Given in the question that the hypotenuse of right angle triangle = 12

To find,

height of the right angle triangle

angle k = 39°

so by using trigonometry identity

cos(39) = opp/hypo

cos(39) = JL / KL

JL = cos(39)(12)

JL = 9.32

JL ≈ 9.3
