lisov135 [29]2 years ago
8 0

Answer:

7.1

Step-by-step explanation:

Since we know this is isosceles triangle (right angle 90 and two 45 degree angles) we know side a and b are equal.

a^2 + b^2 = c^2

5^2 + 5^2 = c^2

25+25= c^2

50 = c^2

c = 7.071 rounded to 7.1

OLga [1]

Answer:

-8j^3+j+2s^3

(4j^3-7j+2s^3)-(-12j^3-8j)

4j^3-7j+2s^3+12j^3+8j

4j^3+12j^3-7j+8j+2s^3

16j^3+j+2s^3
