Answer:

The area of a right-angle triangle is;  Area = a x b / 2

Step-by-step explanation:

A right-angle triangle just like conventional triangle, has three sides.

The sides are labelled a, b and c. With a as the height of the triangle and b as the base and c as the slope or the hypotenuse.

The area of a triangle is: (base/2) x height

This is similar to the area of the right-angle triangle which is also half of the base multiplied by the height of the triangle, that is,

                       Area = ab / 2

Katena32 [7]

Answer:

$189

Step-by-step explanation:

Let their total amount of spending money be x

given that $135 they spent is 5/7 of their total spending money,

mathematically:

135 = (5/7) x     (multiply both sides by 7)

135 (7) = 5x

945 = 5x

5x = 945  (divide both sides by 5)

x = 945 / 5

x = 189

Semenov [28]

Answer:

140,120

Step-by-step explanation:

sum of angles in a quadrilateral =360

sum of the 1st two angles=60+40=100

360-100=260

the ratio of the remaining angles 7:6

therefore:

\frac{7}{13}  \times 260

=140

for the second angle

260-140=120
