Answer:
x = 20
y = 5
Step-by-step explanation:
<u>Adjacent angles of a parallelogram are supplementary</u> (add up to 180°).
So,
6x + 17 + 2x + 3 = 180
Combine like terms
6x + 2x + 17 + 3 = 180
8x + 20 = 180
Subtract 20 to both sides
8x = 180 - 20
8x = 160
Divide 8 to both sides
x = 160 / 8
x = 20
Now,
<u>Opposite sides of parallelogram are equal.</u>
So,
JK = ML
6y - 13 = 32 - 3y
Add 3y and 13 to both sides
6y + 3y = 32 + 13
9y = 45
Divide 9 to both sides
y = 45 / 9
y = 5

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:
Option D.
Step-by-step explanation:
we know that
Angle -135° is equal to
360°-135°=225°
The angle belong to the III quadrant
225°-180°=45°
sin(45°)=d/1=d
therefore
sin(-135°)=-sin(45°)=d ---> the value is negative
