Sum of interior angles of a triangle = 180°
x+40+30= 180°
x+ 70=180
x= 180-70
x= 110°
(2,110)(5,114.5)
slope = (114.5 - 110) / (5 - 2) = 4.5 / 3 = 1.5
y = mx + b
slope(m) = 1.5
use either of ur points..(2,110)...x = 2 and y = 110
now we sub and find b, the y int
110 = 1.5(2) + b
110 = 3 + b
110 - 3 = b
107 = b
so ur equation is : y = 1.5x + 107 <==
Answer:
13.5 cm
Step-by-step explanation:
if 5 cm is 2 km, then 10 cm is 4 km. To find one km you do half of 5 cm. which is 3.5 cm. So 10+3.5=13.5
Answer:
1/2
Step-by-step explanation:
Substitute 1/2 as h you get 16*(1/2) you get 4 and -8*1/2 you get -4 so 4+ -4 = 0
