Answer:
18
Step-by-step explanation:
Assuming the sides are 12 and 38
Since this is a right triangle, we can use trig functions
We know the opp side and the adj side of the angle in questions
tan ? = opp /adj
tan ? = 12/38
Taking the inverse tan of each side
tan ^-1 (tan ?) = tan ^-1 (12/38)
?=17.52556
To the nearest degree
? = 18
If the side is 36,
tan ? = opp /adj
tan ? = 12/36
Taking the inverse tan of each side
tan ^-1 (tan ?) = tan ^-1 (12/36)
?=18.43494
To the nearest degree
? = 18
Answer:
9.1) k = 4.6
9.2) k = 6
Step-by-step explanation:
9.1)
To find constant of proportionality, k, divide both sides by 25
Constant of proportionality, k = 4.6
9.2)
To find constant of proportionality, k, divide both sides by 2.5
Constant of proportionality, k = 6
This can be answered through simple ratio and proportion
Let x = width
y = height
x/y = x2/y2 = x3/y3
since
for 18 inches width we have 26 inches as length, therefore
18/26 = 45/y2
y2 = 65 ft
there is no need to convert the units for the smaller
dimensions since we are dealing with definite ratios thus unitless.
No if you use the equation that it gives then no
