The answer to the question is A
Answer:
B
Step-by-step explanation:
The answer is B, I and IV only
To get to know who will reach fast we need to compare the speed of Andre and Yazmeen.
speed=distance/time
Andre's speed will be:
Distance=11 miles
time=12 min
speed=11/12=0.92 miles/min
Yazmeen's speed:
distance=26 miles
time=24min
speed=26/24=1.08 miles/min
From above calculation we conclude that Yazmeen will reach first because she was traveling at a faster speed that Andre
1) 43
2) 21
step by step:
Both triangles are right triangle which means they're equal to 90.
1) 23+24+X= 90
47+x= 90
x= 90-47
X= 43
2) 30+39+X= 90
69+X= 90
X= 90-69
X= 21
Complementary angles are two angles that add up to 90 degrees
So, 2x + 3x = 90 we have to solve for x
5x = 90
Divide each side by 5
x = 18
Plug 18 into x for 3x and 2x
3x = 3(18) = 54
2x= 2(18) = 36
