Answer:
Diagonal of the rectangle =
Step-by-step explanation:
The length of the diagonal of rectangle can be find by using the Pythagoras theorem as it cuts the rectangle into two equal Right angled triangles,
Given: The length and width of the rectangle are given i.e 40 m and 30 m
According to Pythagorean theorem:
The diagonal of the rectangle becomes the hypotenuse, length becomes perpendicular and width becomes base of the triangle.
So, the length of the diagonal of the rectangle is
The national interest rate on houses for 25 years is 4.3%. The banker wishes to test that the local interest rates are lower than the national rate. So he should use the initial data of 4.3% interest as his base data. Then he should investigate the rates of houses in the local vicinities and compare it to his base data.
Answer:
∠ 4 = 130°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 is an exterior angle of the triangle , so
∠ 4 = ∠ 1 + ∠ 2 ( substitute values )
11x + 9 = 6x + 6 + 4x + 14 , that is
11x + 9 = 10x + 20 ( subtract 10x from both sides )
x + 9 = 20 ( subtract 9 from both sides )
x = 11
Then
∠ 4 = 11x + 9 = 11(11) + 9 = 121 + 9 = 130°
your friend may have only calculated ∠ 1
∠ 1 = 6x + 6 = 6(11) + 6 = 66 + 6 = 72°
