Answer: See Explanation
Step-by-step explanation:
This worksheet seems to be about "Special Right Triangles"
In this worksheet, it instructs you to find the missing side lengths.
Explaining number 1)
Step 1) Identifying the triangle and what it means
Since the triangle in number one is a 45-45-90 triangle with the given side length of "1" on one of the legs of the triangle, it can be concluded that the other leg also has a side length of "1" (due to the ratio of side on a 45-45-90 degree triangle), is also states the triangle has 45 degrees labeled on one of the angles, is can also be concluded that the other missing angle is 45 degrees.
Step 2) Answer
The answer to b is 1 and the answer to a is square root of 2, due to the properties of a 45 45 90 triangle (refer attachment)
*you can also use the following attachment to help you on this problem
The answer is 10. If you replace the number letters with the numbers you get 6 + 10 / 2 - 1. Then you follow PEMDAS, so first divide 10 with 2 to get five (6 + 5 - 1). Add 6 and 5 to get 11 and subtract 1 to get the final answer of 10.
So the left side has a common denominator of 3. The 6x, -2x, and 8 can all go over a single 3. (6x-2x+8/3). Simplify the x's to get 4x. Now both sides have to be multiplied by 3 to get rid of that fraction. Then you just have 4x+8=24. Subtract 8 from both sides to get the x's alone, then divide both sides by 4 to get x alone. I have a picture to help.
The anwser is
4/5x = 16
5/4 x(multiply) 4/5x = 5/4x 16
X= 5x(multiply)4
X=20
(Not 100% sure about the work but the anwser is right)
