Answer:
y = 65°
Step-by-step explanation:
z = 70° (corresponding angels are equal)
y + z = 135° (exterior angle theorem of a triangle)
y + 70 = 135 (substitution)
Subtract 70 from each side
y + 70 - 70 = 135 - 70
y = 65
The difference between 4 and 5 times a number.
4 reduced by 5 times a number.
Answer:
x = 3
Step-by-step explanation:
The triangles are similar, using ratios
x 8
------ = -----------
18 48
We can use cross products to solve
48x = 8*18
48x = 144
Divide each side by 48
48x/48 = 144/48
x =3
Answer:
Area = 260 cm²
Step-by-step explanation:
Area of parallelogram = base × height
Base = 20 cm
Height = 13 cm
Plug in the values
Area of parallelogram = 20 × 13
Area = 260 cm²
48 because 1,200 divide 25 =48 I believe this is right.
