Answer:
Common denominator of 2 and 5 if you want to add or subtract two fractions with 2 and 5 as denominators.
Step-by-step explanation:
Step 1) Take the LCD and divide each denominator by it as follows:
10/2 = 5
10/5 = 2
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 5 = 15
2 x 2 = 4
Step 3) Put it all together to solve the problem:
15/10 + 4/10 = 19/10
= 3/2 + 2/5 = 19/10
=10
Since you’re already given one of the sides of the triangles as well as the triangle’s hypotenuse, you’ll want to find the third side to find the area.
To find the third side length, we’ll use the Pythagorean Theorem:
a^2 + b^2 = c^2
“a” and “b” can be used interchangeably, so we can substitute the known side length of 7 cm into “a”. 25 cm substitutes for “c” since it’s the hypotenuse.
(25)^2 - (7)^2 = c^2
c = 24
Area of triangle = (1/2)bh, where “b” and “h” are interchangeable.
Area of triangle = (1/2)(24)(7) = 84 cm^2
