Answer:
Step-by-step explanation:
sum of all the angles in a triangle=180
let the angles be 2x, 4x and 3x
so, 2x+4x+3x=180
9x=180
x=20
so smallest angle 2x= 2(20)= 40 degrees
Answer:
30.6 cm²
Step-by-step explanation:
The area of the parallelogram is simply the sum of the areas of the component three shapes - the square and the two triangles.
Area of square = 4.5 cm × 4.5 cm = 20.25 cm²
Area of two triangles = 2 ×(1/2) × 2.3 cm × 4.5 cm = 10.35 cm²
Area of parallelogram = 20.25 cm² + 10.35 cm² = 30.6 cm²
