Answer:
32°
Step-by-step explanation:
This is an equilateral triangle which means all three sides of the triangle is equal so is the angles.
Therefore the value of x is : 2x - 4 = 60° ➡ 2x = 64° ➡ x = 32°
When the slope of a line is undefined, it means that the line is either vertical or horizontal. If the x intercept is -7, the equation would be
x = -7
Answer: using A= bh/2 THe height is 9.23
Step-by-step explanation: First, with the Right Angle at the bottom, usr the sides to compute the area: 12*5=60
THen Imagine the side=13 as the base, so you have b=13 for the formula
use the formula A= bh/2
60 = 13h/2 ==> 2(60) =13h --> 120/13 = h
h = 9.23
Answer:
Step-by-step explanation:
We are given the following:
and 
a). Recall that a level curve of a function f(x,y) is given by 
where c is a constant. That is, all the points in the set of interest to which the function applied to the points is exactly the value c.
Consider c = 80. So we get
which implies that 
(Graph 1).
We can also consider c=60, which gives us
which implies that 
. (Graph 2)
b)Recall that the gradient of a function f(x,y) is given by
In this case,
Thus, the gradient of T is given by
