The other person is literally wrong. The answer is D. Supplementary because two angles that add up to 180 are supplementary angles.
Answer:
84%
Step-by-step explanation:
The first step is to write 21 as a fraction of 25, which is simply
21/25
Now we just need to convert this fraction to a percentage :
21/25 = 84
So, 21 is 84% of 25
8/x= 2/5
8•5= 2•x
40=2x
40/2= x
20= x
Both those are drawn to scale.
5. Isosceles right triangle, sides in ratio 1:1:√2 = x:x:24 so x/24=1/√2,
x = 24/√2 = 24(√2/2) = 12√2
Answer: D. 12√2
6. 1:1:√2 = 10 : AB : BC
BC = 10√2
Answer: A. 10√2 ft
