Find the area of a triangle that has a 10cm side and angle of 105 and another side of 13 cm

62.79cm

Step-by-step explanation:

We are using TRIGONOMETRY. To find the area of a triangle with 2 lengths and a non-right angle, we will use the sine rule.

Area of Triangle = 1/2 * a * b * sin(c)

(Where a & b represent our lengths, and sin(c) represents our angle.)

Area of Triangle = 1/2 * 10 * 13 * sin(105)

Area of the Triangle = 62.79cm

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
