Answer:

25cm2

Step-by-step explanation:

Perimeter of triangle = a + a + a = 30cm

So, a = 10cm

Perimeter of rectangle = 2(a + b) = 30cm

A + b = 30/2 = 15cm

So, b = 15 - 10 = 5cm

Area of square = b × b

Area = 5 × 5 = 25cm2

Angle A and Angle B are Complementary Angles. If Angle A measures 40 degrees, what is the measure of Angle B? *
IceJOKER [234]

Answer:

50 degrees

Step-by-step explanation:

If angle A and angle B are complementary, that would mean that their sum is 90 degrees. A + B = 90 . We know that angle A is 40, so 40 + B = 90. It becomes a one step equation. Subtract both sides by 40. 90 - 40 = 50. Angle B is equal to 50 degrees.
