The triangle is an isosceles triangle because of its degrees. A triangle consists of 180 degrees therefore, 180-90-45 simply makes it 45 matching the other side.
So we can assume that side b is also equivalent to side a. Here we use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25+25=50
The square root of 50 is 7.1
x= 7.1
A: 100 cm³
This is because the others can be multiplied by something 3 times to get it, but A can not.
96 units squared
The formula for area:
A = (1/2)bh
Area = (1/2) times base times height
6/15 = 2/c...this is a proportion, so we must cross multiply
(6)(c) = (15)(2)
6c = 30..divide both sides by 6
c = 30/6
c = 5
and if u will notice...6/15 = 2/5...proportions are nothing but equivalent fractions.
