Answer:
The first one is an Obtuse triangle and the second is an Acute isosceles triangle :)
Step-by-step explanation:
Hope this helped!
A^2 + b^2 = c^2....where a and b are the legs, c is the hypotenuse
3^2 + b^2 = 7^2
9 + b^2 = 49
b^2 = 49 - 9
b^2 = 40.....take sqrt of both sides, eliminating the ^2
b = square root of 40 <==
Answer:
98
Step-by-step explanation: Inverse operations
-14 x -7 = 98
98 / 7 = 14
98 / -7 = -14
