Answer:
62.79cm
Step-by-step explanation:
<u>We are using TRIGONOMETRY</u>. 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
Answer:
It's X
Step-by-step explanation:
First, you need to use the distributive property and distribute the 2 inside the parentheses.
2(x + 1) + 3x = 17
2(x) + 2(1) + 3x = 17
2x + 2 + 3x = 17 -Combine like terms
2x + 3x + 2 = 17
5x + 2 = 17 -Subtract 2 from both sides of the equation.
5x + 2 - 2 = 17 - 2
5x = 15 -Finally, divide each side by 5 to find your answer
5x/5 = 15/5
x = 3
Hope this helps you!
