ABCD is a trapezium.
lisabon 2012 [21]

The length of BC is 4.674 m

<u>Explanation:</u>

Given:

Angle A = angle B = 90°

AD = 2.1 m

AB = 1.9 m

CD= 3.2 m

An image is inserted for the reference

According to the figure,

a is the base

b is the height

c is the hypotenuse

Using pythagoras theorm:

a² + b² = c²

a² + (1.9)² = (3.2)²

a² + 3.61 = 10.24

a² = 6.63

a = 2.574

BC = 2.1 + 2.574

BC = 4.674m

Therefore, the length of BC is 4.674 m

How do I solve these two?
Bas_tet [7]

Answer:

1.D

2.B

Step-by-step explanation:

For the first one divide see which one is less which is D

For the second one Ive always used the method kcf keep change flip so you keep \frac{15}{1} the change ÷ to multiplication so then flip \frac{2}{9} so the equation would be

\frac{15}{1}x\frac{9}{2} so multiply the 15 by 9 then you get 135 then divide by 2 so thats your answer
