Question

abcd is a quadrilateral work out angle x HELp

Answer 1

Answer:

• 33.55°

Step-by-step explanation:

Find the length of BD:

• $BD=\sqrt{12^2+5^2}=\sqrt{169} =13\quad cm$

Use the ΔBCD and the law of sines to find the angle x:

• $BD/sin(25)=CD/sin(x)$
• $sin(x)=17*sin(25)/13 = 0.5526$
• $x=arcsin(0.5526)=33.55$
