A label is twice as long as it is wide. If the length of the label is 10 cm, find the area of the label.
O 20 square centimeters
O 50 square centimeters
O 60 square centimeters
O 70 square centimeters

50 square centimeters

Step-by-step explanation:

Long means length, and we know the length of the label, 10 centimeters. That means the width is half of 10 centimeters, or 5 centimeters. Now, we multiply 10 and 5 to get 50. That means the area of the label is 50 square centimeters

45° for both

Step-by-step explanation:

Angles in a triangle add to 180° and there is two angles labelled x and one right angle so

2x + 90° = 180°

( Minus 90 from both sides to isolate 2x )

2x = 90°

( Divide both sides by 2 to isolate x )

x = 45°
