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
2m - 6 = 8m
2m - 6 - 2m = 8m - 2m
2m - 2m - 6 = 8m - 2m
-6 = 6m
-6/6 = 6m/6
-1 = m
-1(3) = m(3)
-3 = 3m
3m = -3
Answer:
the number is 25
Step-by-step explanation:
If the number is n, then twenty-two more is n + 22
which equals 47, so n+ 22 = 47
n = 47 - 22 = 25
The answer is both A and B
