How do I find the angle measure for 2?
1 answer:
Answer: 139 degrees
Step-by-step explanation:
First you must find the measure of each angle within the triangle.
82 + (9x-6) + (6x-1) = 180
15x + 75 = 180
15x = 105
x = 7
Plug 7 in for the value of x for the angle adjacent to angle 2
(6(7) - 1)
42-1
41 degrees
Now we know that supplemental angles equal 180 (to form a straight line). We can now calculate the measure of angle 2
180-41 = angle 2
angle 2 = 139 degrees

A^2+B^3=c^2
6^2+8^2=c^2
36+16=c^2
52=c^2
Square root both sides
7.2=C
Answer:
when they cross u should get a perfect solution of (2,6)
It equals 0.1365853659
you may round as needed
You must multiply each number for example 8*4*2= 64 so the after math is 64 after all the work the answer is ^4.
