Answer:
50°
Step-by-step explanation:
The internal angles on a quadrilateral sum to 360.
So x+10+2x+x+3x=360
7x+10=360
7x=350
x=50
Answer:
135°
Step-by-step explanation:
Using S = rA, where S is arc length, r is radius and A is angle(in radians).
Comparing:
=> 12 = 16A
=> 12/16 = A
=> 3/4 = A
Required radian is 3/4 which is 3/4 * 180° = 135°
Answer:
C
Step-by-step explanation:
according to sine rule,
sin(30)/8=sin(x)/11
solving above equation will give
x=43.3
Answer:
270 degrees counterclockwise rotation/ the last answer
Step-by-step explanation:
reflection over the y axis wouldn't work bc the shape would still be a horizontal rectangle
dilation would change the size of the shape
and translation wouldn't map it correctly bc it would still be turned the wrong way
