Please help I don’t understand it’s like angles and stuff picture above.
dusya [7]

Answer:

1) 145°

2) 20°

3) x = 7 ; measurement of the missing angle = 24

Step-by-step explanation:

1) supplement = 180°, 180 - 35 = 145

2) complment = 90° , 90 - 70 = 20

3) the figure is a right angle so the measurement is 90°

66 + (4x-4) = 90

62 + 4x = 90

4x = 28

x = 7

4(7) - 4

28 - 4

= 24

Option B is the correct answer

Step-by-step explanation:

Hope it helps you in your learning process.

\implies\huge{\red{ x={17\sqrt 3}}}

\sin 30\degree=\frac{17}{y}

\implies\frac{1}{2}=\frac{17}{y}
