Answer:
60 miles per hour
Step-by-step explanation:
For each point just divide the miles by the hour
120/2 = 60 mph
180/3 = 60 mph
240/4 = 60 mph
3x+3=90
subtract 3 from both sides
3x=87
divide both sides by 3
x=29
To find IJ, plug in the x value
x+8+x-9
29+8+29-9
57=IJ
I think is 12??? because area is l×w
Your choices of answers are not clear, is the letter x a variable or a multiplication?
If it is possible, take a picture of your question.
Answer:
x ≈ 61.3
Step-by-step explanation:
Using the Sine rule, that is
= 
( cross- multiply )
5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )
sin x = 
≈ 0.87729, thus
x = 
(0.87729) ≈ 61.3
