A. jgb=jb+Eh/2
35+45=80/2=40 JGB =40°
B. since it is a line HGJ =180-40
HGJ= 140°
C. tangents to circles have equal lengths if they intercept the way gd and gf do eachother
set the lengths equal to themselves
4x+5=6x-8
-4x both sides
5=2x-8
+8 both sides
13=2x
÷2 both sides
x=13/2 or 6.5
Plug in
4 (6.5)+5=
26+5=31ft
You must do 1/2 times base times height
Answer:1:1000
Step-by-step explanation:
It’s 1:1000 because compared to the other one the height of the model would be 9.3 centimeters if 1:1000 was the scale of the model
36+27i because /-9/ equals 9 so you distribute 9 in the parentheses then you add like terms
