The angles in a triangle are in the ratio 1:2:3 a) Show that the triangle is a right -angled triangle b) The hypotenuse of the triangle is 19cm long. Calculate the length of the shortest side in the triangle

8.5 cm

Step-by-step explanation:

Angles of the triangle:

Right triangle as it has 90° angle

Sides are a, b and 19 cm

47 - 90 = 43

43 - 180 = x

x = 137

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees
