B is 30
C is 720
D is 360
The measures of
1=105 degrees and 2=75 degrees
Answer:
Solve for
n
by simplifying both sides of the equation, then isolating the variable.
n
=
2
Step-by-step explanation:
Answer:
a= 20
b= 169.7
c= 29.71
Step-by-step explanation:
The formula of a triangle is (h*b)/2
a= (5*8)/2
b= to find the height, you can use the pythagorean theorem 18^2 - 6^2 = square root of 288. Which is 12root 2 or 16.97. (16.97*20)/2
c= using the pythagorean theorem- 11^2 = 7^2 - c^2 = square root 73, or 6root 2, or 8.49. (8.49* 7)/2
80%x + x = 216
0.8x + x = 216
1.8x = 216
x = 216/1.8
x = 120
