Answer:
x=80
Step-by-step explanation:
The sum of interior angles in a quadrilateral is 360°
the square represents a right angle= 90 degrees
124+66+90=280
360-280=80
x=80
Answer:
16.75%
Step-by-step explanation:
find the difference:
23000 - 19700 = 3300
no divide 3300 by 19700 to get the percent
3300 / 19700 = 0.1675
move decimal twice for percent
16.75%
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:
