Answer:
40
Step-by-step explanation:
180 -40 - 90 = 50
I don't remember the name of the type of angle, but since that one angle is 50 the other side is also 50.
180 - 90 - 50 = 40
Tell me if I am wrong.

Find, corrrect to the nearest degree, the three angles of the triangle with the given vertices. D(0,1,1), E(-2,4,3), C(1,2,-1)
Sholpan [36]
Answer:
The three angles of the triangle given above are 23, 73 and 84 correct to the nearest degree. The concept of dot product under vectors was applied in solving this problem. The three positions forming the triangle were taken as positions vectors. The Dot product also known as scalar product is a very good way of finding the angle between two vectors. ( in this case the sides of the triangle given above). Below is a picture of the step by step procedure of the solution.
Step-by-step explanation:
The first thing to do is to treat the given positions in space as position vectors which gives us room to perform vector manipulations on them. Next we calculate the magnitude of the position vector which is the square root of the sun of the square of the positions of the vectors along the three respective axes). Then we calculate the dot product. After this is calculated the angle can then be found easily using formula for the dot product.

Answer:
Infinite number of solutions
Step-by-step explanation:

For any value of x, both equations are equal to each other because both sides are identical
Answer:
I went shopping once for ingredients of a cake, but i didn't know what my finale price would be. So i estimated what the total cost could be, then i took all the prices and added them up then divided the price by how many ingredients i got to find the average and it was pretty close to my estimate. So math can help when you go shopping. (Sorry if how i find my prices is weird, i kinda just stand in one spot for at least 5 - 8 mins trying to find my price)
