Answer:
1. adjacent: ∠ACB and ∠BCD.
vertical: ∠ACB and ∠ECD
Step-by-step explanation:
Alright, so if the length of one of the equal sides are x, 2x-2 is the base and x+x+2x-2=98=4x-2. Adding 2 to both sides, we get 100=4x and dividing by 4 we get 25 as one of the equal sides and 48 as the base. Since we need to find the height to find the area, we can draw a line straight down the middle to form 2 right triangles, with the hypotenuse being 25 and the base being 48/2=24. Therefore, since a^2+b^2=c^2 and 24^2+b^2=25^2, we have
25^2-24^2=49=b^2. Square rooting both sides, we get b=7=height, and the base*height/2 is the area, so we get 48*7/2=168 as the area
The answer would be 10.8
9/5=x/6
Cross multiply
5x=54
Divide by 5
x=10.8
The sum of all the angles of a triangle is 180 degrees.
If you add 90 + 90 + 90 together you get 270. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.
If you add 80 + 80 + 200 together you get 360. These can not be the angle measures of interior angles of a triangle because the sum is more then 180.
If you add 40 + 50 + 60 together you get 150. These can not be the angle measures of interior angles of a triangle because the sum is less then 180.
If you add 15 +30 + 135 together you get 180! This set of angle measures can the be interior angles of a triangle!
Hope this helped!

Answer:
2
Step-by-step explanation:
A coefficient is the number placed before the variable. The variable gets multiplied by the coefficient.
The format is not exactly clear with the expression in the question.
Assuming the expression is '8 * 2n', the coefficient would be 2.
'n' is getting multiplied by '2'.
'8' does not have a variable next to it, so it is just a term in the expression.
The product of 8 and 2 is 16. 16 is not in the expression.
If the expression was '8.2n', 8.2 would be the coefficient.
