If two angles are equal and supplementary, the angles are A. acute angles B. right angles C. acute angles

right angles.B

Step-by-step explanation:

let x and ybe angles.

x+y=180

also x=y

x+x=180

2x=180

x=180/2=90

y=x=90

right angles

Step-by-step explanation:

Let x be the angle

X is also the other angle since they are equal

Supplementary means they add to 180

x+x = 180

2x = 180

Divide by 2

2x/2 = 180/2

x= 90

They are right angles

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
