Once you know the height and width, multiply them to get the area of the square.<span> To </span>find<span> the perimeter of the square, add all four sides </span>together. <span>To </span>find the area of a triangle<span>, multiply </span>together<span> two of the sides not the hypotenuse and then multiply that figure by 1/2.</span>
X would be -14. i’m hoping that’s what you need
The first one is the answer. Hope i helped you, have a blessed day :)
If you represent the problem in a diagram, you will form a triangle with 3 known length of the sides. When you are given all sides, and you are asked to find an angle, you can use the cosine law.
b^2 = a^2 + c^2 - 2ac*cosB
1.4^2 = 1.9^2 + 1^2 - 2(1.9*1)(cosB)
B = 45.78°
