Answer:
The angles in the triangle and 10, 80 and 90
Step-by-step explanation:
The two angles that are left in a right triangle add to 90 degrees
8:1 means that there total is 9
8x+1x = 9x
9x = 90
Divide by 9
9x/9 = 90/9
x = 10
8*10 = 80
1*10 = 10
The angles are 80 and 10
The angles in the triangle and 10, 80 and 90
I think it is C, I don't think it is B
Answer:
8
Step-by-step explanation:
area of a triangle= b x h x 1/2 or b x h /2
the base is 4 and the height is 4
4x4/2
=16/2
=8
the domain is the numbers you can use for x
x is how many papers you can buy
you can't buy negative papers
but the store only has 5 papers so the answer is all inegers from 1 to 5 including 1 and 5
integes are like -3,-2,-1,0,,2,3,4, but since we have 1 to 5 we have 1,2,3,4,5
it isn't all real numbers from 1 to 5 because you can't buy 3.141592 reams of paper
answer is first one
