Draw triangle

Construct an isosceles triangle ABC, if AB = 7cm, the size of the angle ABC is 47°, arms | AC | = | BC |. Measure the size of the BC side in mm.

Correct answer:

x =  51.32 mm

Step-by-step explanation:

$x=51.32={\displaystyle \frac{1283}{25}}={\displaystyle \frac{1283}{25}}\text{ mm}=51.32\text{ mm}$
