Question

1) What can be concluded about the triangle whose two angles are 58° and 65°?
2)The base of a triangle is 12 cm and its area is 48 sq. cm, then find the height of the triangle?

Answer 1

Answer:

1. Scalene triangle, 2. 8cm

Step-by-step explanation:

1. The third angle of the triangle is 180°-(58°+65°)

=180°-123°

= 57°

Therefore it is a scalene triangle

2. Let height is x cm.

Therefore, Area of the triangle=1/2×base ×height

or, 48sq.cm =1/2×12cm.× x

or, x=48/6cm

or, x=6cm
