I do not understand how to work out this question please help

a) To find the missing side length on triangle A, we can use the Pythagorean theorem.

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = 5 cm

5 and 12 = 5 and 12

b) The two triangles are congruent because they have two side lengths in common. If at least two side lengths are the same on two triangles, then they are congruent. In addition, these triangles have one angle in common as well.

Hope this helps!! :)

How do I do this please help
Umnica [9.8K]

Answer:

wrong as his calculation was incorrect at initial level itself when he found the result of the division

Step-by-step explanation:

Andre said

3 ÷ \frac{2}{3}

=3 \times \frac{3}{2}

=\frac{3 \times 3}{2}

=\frac{9}{2}

but andre calculated it as

=4\tfrac{1}{3}

=\frac{4 \times 3 + 1}{3}

=\frac{13}{3}

Hence his calculation was incorrect at initial level itself
