48 + 42 + x = 180
90 + x = 180
180 - 90 = x
x = 90 degrees

Answer:
Reflection and a Dilation (I'm not too sure if this is correct hopefully it helps)
Step-by-step explanation:
<u>Ans(a):</u>
Given that total distance = 1158 km
Estimated time of drive = 12
now question says to distance that can be driven in 1 hour.
Indirectly it is asking for his speed.
So we can use formula of speed
km per hour.
Hence he will drive approx 96.5 km in 1 hour.
<u>Ans(b):</u>
Actual driven distance = 484 km
Actual time taken = 5 hours
Then actual speed
km per hour
Comparing speeds in both parts, we see that actual speed 96.8 km/hour is more than the expected speed 96.5 km/hour.
Hence he will reach at his destination on schedule or before the expected time.
Answer:
The domain is all real numbers
Step-by-step explanation:
f(x) = x^2 +6x +8
The domain is what numbers can we put in for x
This is a parabola, we can put in any number for x and the function is defined
