Answer:
1
Step-by-step explanation:
x+y=1 if x=0, then y=1
Answer:
Part a) <1=72°
Part b) <2=108°
Part c) <3=72°
Part d) <4=108°
Step-by-step explanation:
step 1
Find the measure of angle 1
we know that
<1+108°=180° -----> by supplementary angles
so
<1=180°-108°=72°
step 2
Find the measure angle 2
we know that
<2=108° -----> by corresponding angles
step 3
Find the measure angle 3
we know that
<3=<1-----> by corresponding angles
so
<3=72°
step 4
Find the measure angle 4
we know that
<4=108° -----> by alternate exterior angles

Find area of one triangle
---------------------------------------------
Area of triangle = 1/2 x base x height
Area of triangle = 1/2 x 9 x 11.75
Area of triangle = 52.875 ft²
---------------------------------------------
Find area of two triangles
---------------------------------------------
Area of 2 triangles = 52.875 x 2
Area of 2 triangles = 105.75 ft²

Find the cost of the flower beds
---------------------------------------------
1 ft² = $4.25
105.75 ft² = 105.75 x 4.25
105.75 ft² = $449.44 (nearest hundredth)

Answer:
86 cm
Step-by-step explanation:
parameter of the Pentagon
= the parameter of the square + the parameter of the
triangle
= 48 + 38
= 86
