Answer:
20m
Step-by-step explanation:
If f(x)=2x-1 just plug in the 3 where x is. So it would be 2(3)-1=5
Area is equals length times (*) breath
L*b
10.3*9.3
=95.79l
The two unknown sides are equal to each other so then the two unknown angles are also equal.
A triangle angles add up to 180
36 + 2x = 180
2x = 180 - 36
2x = 144
unknown angles x = 72°
draw line down center of triangle to make two right triangles with side 22/2 = 11. SOH CAH TOA
cos(72) = 11/H
H = 11/cos(72)
H = 35.6
perimeter = 22 + 2(35.6)
perimeter = 93.2 cm
answer E .
