Complementary
Step-by-step explanation:
Angle 1 and 2 make up a 90-degree angle
Hope this helps! :)
First, let's find the time where the ship arrives to point C
t=d/V, t= 45/30=1.5h
if the ship's departure time is at 1.5h, on the point C, let 's find its arrival to the point O, V=D/Dt, Dt=tfinal-tinitial
Dt=D/V= 20/30=0.6h=t final -t initial, implies t final=0.6+t initial=0.6+1.5=2.1h
so the ship will be on the radar at 2.1h,
Answer:
x = 75
Step-by-step explanation:
Corresponding angles on the same side of the transversal are equal
10x + 5 = 12x - 9 Add 9 to both sides
10x + 5 + 9 = 12x Combine
10x + 14 = 12x Subtract 10x from both sides
14 = 12x - 10x Combine
14 = 2x Divide by 2
2x = 14
x = 14/2
x = 7
==================
10x + 5 = 10*7 + 5
10x + 5 = 75
12x - 9 = 12*7 - 9
12x - 9 = 84 - 9
12x - 9 = 75
In my opinion the answer is <span>m2 – 100 = –99
proof
</span>m2 – 100 =<span>(m – 10)(m + 10)
for eg. m=1, </span>(-9)(11)= <span>–99</span>
