Answer:
angle ABC is 48⁰
Step-by-step explanation:
angle BCD will be 111⁰ it will be equal to DAB.
111+111+90=312⁰
kite is a quadrilateral so its angles add up to 360⁰
360-312=48⁰
<h2>ΔABC = 48°</h2><h2>_____________________</h2>
<u>Step-by-step explanation:</u>
ΔA = ΔC = 111° (<em>k</em><em>i</em><em>t</em><em>e</em><em> </em><em>p</em><em>r</em><em>o</em><em>p</em><em>e</em><em>r</em><em>t</em><em>y</em><em>-</em><em>o</em><em>p</em><em>p</em><em>o</em><em>s</em><em>i</em><em>t</em><em>e</em><em> </em><em>Δ</em><em> </em><em>e</em><em>q</em><em>u</em><em>a</em><em>l</em><em>)</em>
ΔD = 90° ------ ( <em>g</em><em>i</em><em>v</em><em>e</em><em>n</em><em> </em><em>)</em>
ΔA + ΔB + ΔC + ΔD = 360°
111° + ΔB + 111° + 90° = 360°
312° + ΔB = 360°
ΔB = 360° - 312°
ΔB = 48°
