Answer:
<em>Angle B=90 degrees</em>
<em> </em>
<em>BA^C= 40 degrees</em>
Step-by-step explanation:
<em>Angle B=</em><em>90 degrees (</em><em>right angle =90 degrees</em><em>)</em>
<em />
<em>90+50+BA^C=180</em>
<em>140+BA^C =180</em>
<em> BA^C=180-140</em>
<em> </em><em>BA^C= 40 degrees</em>
<em> </em>
Answer:
The answer is C
Step-by-step explanation:
Answer:
The measure of arc HD is 20°
Step-by-step explanation:
we know that
The measurement of the outer angle is the semi-difference of the arcs it encompasses.
In the triangle of the figure , the measure of the third interior angle is equal to
180°-92°-38°= 50°
50°=(1/2)[(102+18)°-arc HD]
100°=[120°-arc HD]
arc HD=120°-100°=20°
