Answer:
x= 6
Step-by-step explanation:
You will subtract 10x from 12x and get 2x
Subtract 4 from 16 to get 12
You will then divide both sides by 2
= 
x= 6
The second one is hard to read but since ∠3 is 54° you should just start from there
Hope this helps
Answer:
Two angles that have the same measure are called congruent angles. Here are two angles that both measure 30°. We say that angle x is congruent to angle y.
Step-by-step explanation:
Answer:
yes because any input of time results in only one output of altitude
yes because the airplane increases and decreases in altitude at the same rate
pick either one :>
Let's assume they meant C=40 degrees. With an angle like that they're asking for approximation; we'll oblige.
The circumradius is the product of the triangle sides divided by four times the area.
Here we have remaining side given by the Law of Cosines.
The area is
The circumradius is
X^2 - 4x + 2
d = b^2 - 4ac, where a = 1, b = -4 and c = 2
d = (-4)^2 - 4 x 1 x 2
d = 16 - 8
d = 8
