Answer:
42
Step-by-step explanation:
so 180-132 will give u top angle of triangle
which is 48 degrees
48+90+x=180
180-90-48=x
x= 42
Answer:
The greatest number of acres used for wheat = 7 acres .
Step-by-step explanation:
The maximum number of land used by farmer to plant = 28 acres .
Let the land used to plant wheat = x .
So the land to plant trees will be = 3x .
Now ,
x + 3x = 28 acres .
4x = 28 acres.
x = 7 acres
∴ Hence the greatest number of acres used for wheat = 7 acres .
Answer:
≈ 50.7 cm²
Step-by-step explanation:
The area (A) of Δ XYZ is calculated as
A =
bh ( b is the base and h the perpendicular height ), that is
A =
× XY × YZ
Calculate YZ using the tangent ratio in the right triangle
tan40° =
=
=
( multiply both sides by 11 )
11 × tan40° = x , that is
YZ ≈ 9.23 cm
Thus
A =
× 11 × 9.23 = 5.5 × 9.23 ≈ 50.7 cm² ( to 3 significant figures )
Y=3/1x+-1 hope this is correct
