Answer: 39 degrees
Step-by-step explanation:
Since the triangle is a right angle
The sum of angles in a right angle is 90degrees
51degrees + A= 90 degrees
A= 90degrees - 51 degrees
A=39 degrees
Answer:
x=7
Step-by-step explanation:
Opposite of subtraction is adding so you do 4+10=14 so that means that x equals seven because 2x7 equals 14.
Answer:
w = 1.6
Step-by-step explanation:
Given w varies inversely as
then the equation relating them is
w =
← k is the constant of variation
To find k use the condition when x = 4, w = 4
k = w
= 4 ×
= 4 × 2 = 8
w =
← equation of variation
When x = 25, then
w =
=
= 1.6
